scala scalajs time timezones

scala-java-time's Introduction

Scala Java-Time

This project provides an implementation of the java.time package, a date and time library that was added in Java 8. The implementation is based on the original BSD-licensed reference implementation (before it was contributed to OpenJDK).

Usage

The scala-java-time library is currently available for Scala (JVM, version 8 and later), Scala.js (JavaScript) and Scala Native (LLVM). Scala 2.11, Scala 2.12, Scala 2.13 and Scala 3.0.0 are supported.

To get started with SBT, add one (or both) of these dependencies:

libraryDependencies += "io.github.cquiroz" %%% "scala-java-time" % "2.5.0"

scala-java-time's Issues

Regression test for 2.0.0-RC5

The following tests used to work with dependencies

    "io.github.cquiroz" %%% "scala-java-time" % "2.0.0-M13",
    "io.github.cquiroz" %%% "scala-java-time-tzdb" % "2.0.0-M13_2018c", // ToDo: filter timezones

but fail with dependencies

    "io.github.cquiroz" %%% "scala-java-time" % "2.0.0-RC5",
    "io.github.cquiroz" %%% "scala-java-time-tzdb" % "2.0.0-RC3_2019a", // ToDo: filter timezones

     "with predefined formatters" - {
        "formatFullDate" - {
          assertResult("January 30, 2018") {dt.format(formatFullDate)}
        }
        "formatDayOfWeek" - {
          assertResult("Tuesday Jan. 30") {dt.format(formatDayOfWeek)}
        }
        "formatTime_AM_PM" - {
          assertResult("11:02 AM") {dt.format(formatTime_AM_PM)}
        }
      }

where dt is defined as LocalDateTime.of(2018, 1, 30, 11, 2, 45, 750000)
and the formatters as

  val formatFullDate = DateTimeFormatter.ofPattern("MMMM dd, yyyy")

  val formatDayOfWeek = DateTimeFormatter.ofPattern("cccc MMM. d")   // Thursday Jan. 25

  val formatTime_AM_PM = DateTimeFormatter.ofPattern("h:mm a")    // 10:15 PM

The output I'm now getting from the tests is

X oat.xplatform.javaTime.JavaTimeTests.Formatting LocalDateTime.with predefined formatters.formatFullDate 4ms
  utest.AssertionError: utest.assert(actual == expected)
  actual: Any = M01 30, 2018
  expected: T = January 30, 2018
X oat.xplatform.javaTime.JavaTimeTests.Formatting LocalDateTime.with predefined formatters.formatDayOfWeek 3ms
  utest.AssertionError: utest.assert(actual == expected)
  actual: Any = Tue . 30
  expected: T = Tuesday Jan. 30
X oat.xplatform.javaTime.JavaTimeTests.Formatting LocalDateTime.with predefined formatters.formatTime_AM_PM 2ms
  utest.AssertionError: utest.assert(actual == expected)
  actual: Any = 11:02
  expected: T = 11:02 AM

I spent some time with the scala-java-time code to see if I could at least write a test, but couldn't get it figured out in a reasonable amount of time. Sorry.

Thanks for your fantastic work.

Support timezones using generated code

Publish artifacts for Scala.js 1.0.0-RC1 and 1.0.0-RC2

Scala.js v1.0.0-RC1/RC2 were released. It would be great to publish artifacts for these releases.

Deploy scala-java-time 2.0.0-M19 for Scala 2.11

scala-java-time doesn't appear to be deployed for Scala 2.11 (can't retrieve and dependencies).

Missing methods for JDK9+

While using java.time.Duration, several methods added after Java 8 was not implemented.
For example:

public long dividedBy(Duration divisor)
public int to*Part()

I assume there are a few more scattered around in java.time.

The implementation for most of them are trivial.
I'm not sure whether the licence allows copying and pasting directly from OpenJDK source.
If it is, I'll just open a PR and fill in all the new methods.

ZoneRulesException without timezone

The following code works in scala: LocalDateTime.now().
But in Scalajs it throws: java.time.zone.ZoneRulesException: Unknown time-zone ID: Europe/Oslo.
I do not intend to use any timezone.
Scalajs version: 1.5.0
scala-java-time version: 2.1.0

Remove java.util.Calendar

scala-java-time contains a half-baked implementation of java.util.Calendar. That class is fairly large and contains many quirks, completing it will be a major task. Instead I propose to remove it, leaving only the static constants. The current implementation contains a minimum of code to support some parts of the code

Inspection of the code reveal this change will involve moving the JapaneseChronology and JapaneseEra classes to be jvm only. At any rate given how broken Calendar is, they likely don't work properly

IMHO we shouldn't ship classes not properly implemented

support Scala 2.13.0-RC1

Publish artifacts for scala-native 0.4.3

The most recent artifact for scala-java-time native is scala-java-time_native0.4_2.13

Would it be possible to publish it for scala-native 0.4.3 and scala library 3+? For now I get

Error downloading io.github.cquiroz:scala-java-time_native0.4_3:2.3.0

Create a gitter channel

Should create a gitter channel for discussing the library

Scala Native 0.5 release

Is the release for 0.5 planned anytime soon? With the libraries slowly publishing for it, the lack of scala-java-time for 0.5 would be a blocker for some libraries.

3.x compilation

scala-java-time is a dependency for zio and zio now has 3.x support.

Anyway to add 3.x published supported for scala-java-time? While withDottyCompat will probably work, it would be good to get this lib on track for the 3.x series.

Same comment for scala-java-time-tzb.

Port unit tests to scalatest

TestNG will likely be never be fully compatible with scala.js

Support custom tzdb modules

ZoneId parsing error messages differ from those of java.time

For example, on the JVM:

scala> java.time.ZoneId.of("X")
java.time.DateTimeException: Invalid ID for ZoneOffset, invalid format: X
  at java.base/java.time.ZoneOffset.of(ZoneOffset.java:241)
  at java.base/java.time.ZoneId.of(ZoneId.java:402)
  at java.base/java.time.ZoneId.of(ZoneId.java:356)
  ... 36 elided

While with scala-java-time on Scala.js the message is Invalid zone: X.

Proposal for JS for implementing .now() without tzdb for all "time" classes except for ZonedDateTime

With these helpers on JS (browsers, node.js), we obtain an OffsetDateTime.now() equivalent (of course up to millisecond resolution due to JS nature) without the need to add tzdb. This unlocks all of {LocalDate, LocalDateTime, LocalTime, MonthDay, OffsetDateTime, OffsetTime, Year, YearMonth}.now() straightforward implementations in terms of the OffsetDateTime.now() instance. And only ZonedDateTime, which intuitively should be the only one that requires actual tz data is left with that need.

def utcOffsetSeconds(ms: Long) = -new Date(ms.toDouble).getTimezoneOffset().toInt * 60

def offsetDateTimeInDefaultTimeZone(instant: Instant) = instant.atOffset(ZoneOffset.ofTotalSeconds(utcOffsetSeconds(instant.toEpochMilli)))

def offsetDateTimeInDefaultTimeZoneNow() = offsetDateTimeInDefaultTimeZone(Instant.now())

What do you think about this?

Publish for scala 2.13.0

OffsetDateTime.now not emitting error anymore, but works wrong

Hi,
first of all million thanks for getting tz support out! Dunno if this is really a bug or just a feature which is still missing:

using scalajs OffsetDateTime.now is not throwing an error anymore, but the system default offset seems to be calculated wrong (or not at all?), it will always be +00 as it seems

Scala.js source maps point to wrong root

JS Source maps for threetenbp and scalajs-locales point to wrong local root /Users/cquiroz/Projects. I think this should point to raw.githubusercontent.com similar to cats: typelevel/cats#916

publish for Scala 2.13.0-M5, please?

because over at bkirwi/decline#47 I'm seeing [error] (declineJS / update) sbt.librarymanagement.ResolveException: unresolved dependency: io.github.cquiroz#scala-java-time_sjs0.6_2.13.0-M5;2.0.0-M13: not found

any expected but <notype> found for tree of type org.scalajs.ir.Trees$Block

Hi, I'm having an issue in scala-java-time/core/js/target/scala-3.0.0/src_managed/main/org/threeten/bp/format/DateTimeFormatterBuilder.scala(1536:4:Labeled)

The error given is: any expected but found for tree of type org.scalajs.ir.Trees$Block

Any ideas on how to solve this?

Using scala version 3.0.0
and version: 2.3.0 of this library

Thank you

Unexpected formatting of Duration for negative nanos and munutes/hours

The following test fails:

assertEquals(Duration.parse("PT-201188937963H-26M-59.667S").toString, "PT-201188937963H-26M-59.667S")

The corresponding bug was fixed in JDK: https://bugs.openjdk.java.net/browse/JDK-8054978

Thank You!

Carlos -- Just wanted to say a huge "Thank you" for all the work you've put into scala-java-time. I'm in the midst of converting my project to use it. It is cleaning up a mountain of past heartaches. Thanks!

UndefinedBehaviorError: java.lang.ArrayIndexOutOfBoundsException: 0

import java.time.LocalDateTime
import java.time.format.DateTimeFormatterBuilder
import java.time.temporal.ChronoField
import java.time.format.TextStyle
import java.util.Locale
import java.time.format.DateTimeFormatter

    .toFormatter(Locale.forLanguageTag("uk"))
val today = LocalDate.now(ZoneId.of("UTC"))
val todayString = today.format(formatterFull)
print(todayString)

This code works on JVM but fails with UndefinedBehaviorError on Scala.js

Some missing format symbols

I found some (obscure) formatting fields that are missing from this reference: https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/time/format/DateTimeFormatter.html#patterns

g - modified-julian-date-number
B - period-of-day
v - generic time-zone name

After comparing different versions of the docs it looks like they were added in different versions between 8 and 11.

It would be nice to get rid of scala-reflect

Hi,

I'm running my Scala apps on AWS Lambda and there is a very strict limit on classpath jars size. scala-java-time is the only library which depends on scala-reflect.

From what I can see it should be possible to remove reflection. Could you please consider that?

Experiment with TC39 Temporal proposal

This is a proposal for a JS-native date/time API:

We should investigate implementing the java.time.* APIs in terms of Temporal. If successful, it may improve performance and more importantly help solve #69 by reducing the size of the generated JS code.

Although the Temporal APIs are not yet available it is in the process of implementation in browsers and the API is not expected to change.

There are currently polyfills which we can target for initial experiments. In http4s/http4s-dom#30 (comment) I estimated the size of scala-java-time to be roughly 100kb; meanwhile, this polyfill boasts a size of 15 kb. So that's something to think about :)

2018f tzdb breaks the parser

Make HijrahChronology work on scala.js

Threetenbp implementation of HijrahChronology depends on java.io.File making it unsuitable to run on scala.js

Update to Scala.js 0.6.16

Should update to the latest version of scala.js, seeing as 0.6.16 is also the last bin compatible version in the 0.6.x series of scala.js

NotImplementedError when formatting in ScalaJS

When formating a date time using the java.time. prefixed classes in ScalaJS I'm getting a NotImplementedError at method DateTimeFormatter.formatTo:

Can't really tell at what point inside that method the code is failing (or even if the code arrives to it) as the lack of sourcemaps in the java.time renamed classes makes it very difficult to debug. The thing is that the same code works if using org.threeten.bp. The application where this is used is a ScalaJS-only web frontend, deals with a lot of dates and times and everything else seems to work just fine, except formatting them.

`Duration` is not `Comparable`

It's not possible to use compareTo on Durations.

Looks like it implements Scala's Ordered but not Java's Comparable

Remove unimplemented methods

Before RC1 all the methods marked with a ??? should be removed or properly implemented

Publish artifacts for Scala.js 1.0.0

Scala.js 1.0.0 has been released, so it would be great to publish artifacts for this Scala.js release.

Auto-generated tzdb_*.scala seems broken

I tried to compile the latest source (https://github.com/cquiroz/scala-java-time/tree/b58861fa7df8c1fec6bc881547d94e2c70992d70) and got the compilation error as below

It is due to the generated tzdb_java.scala and tzdb_threeten.scala contains ... throughout the text.

Support for Scala Native

Hopefully it should be easy to support Scala Native also.

Update tzdb parser

As discussed on gitter

@cquiroz I got it to work by setting dbVersion := TzdbPlugin.Version("2018c") - So it seems that the tzdb format has changed in tzdb in 2018{d,e} and your parser somehow does not understand that change.
If you manually start a travis build, I bet that the tests will fail.

Thanks @ahjohannessen for reporting this

Unknown timezone id

Hi there, thanks for this library!
When I try to run my JS project, I get a "Unknown time-zone ID: Europe/London" exception.
Any idea?

Very large JS file when using Instant.ofEpochMilli

I noticed that when I want to create the current LocalDate using the following:

val offset = ZoneOffset.ofHours(0)
val date = LocalDate.now(clock)

then the generated fastOptJs file is 5.9 MB big. When I instead use

val date = LocalDate.of(2016,1,1)

then the JS file is only 2.7 MB big and generating it is a lot faster.

I tried to find out what exactly is the cause of this problem and got so far that just including this single line of code has the result of making the JS file bigger:

val instant = Instant.ofEpochMilli(0)

However, I can't see anything special in the implementation of this method.

I assume that it has something to do with Locales being included in the JS file, since I see many lines like this one in the large version of the generated output only:

var xs$53 = new $c_sjs_js_WrappedArray().init___sjs_js_Array([new $c_Llocales_cldr_CurrencyDisplayName().init___T__s_Option("Brazilian New Cruzado (1989\u20131990)", $m_s_None$()), new $c_Llocales_cldr_CurrencyDisplayName().init___T__s_Option("Brazilian new cruzado (1989\u20131990)", new $c_s_Some().init___O("one")), new $c_Llocales_cldr_CurrencyDisplayName().init___T__s_Option("Brazilian new cruzados (1989\u20131990)", new $c_s_Some().init___O("other"))]);
  var this$120 = $m_sci_List$();
  var cbf$53 = this$120.ReusableCBFInstance$2;
  var jsx$502 = new $c_Llocales_cldr_NumberCurrency().init___T__sc_Seq__sc_Seq("BRN", jsx$503, $as_sci_List($s_sc_TraversableLike$class__to__sc_TraversableLike__scg_CanBuildFrom__O(xs$53, cbf$53)));
  var jsx$501 = $m_sci_Nil$();
  $m_sci_List$();
  var xs$54 = new $c_sjs_js_WrappedArray().init___sjs_js_Array([new $c_Llocales_cldr_CurrencyDisplayName().init___T__s_Option("Brazilian Cruzeiro (1993\u20131994)", $m_s_None$()), new $c_Llocales_cldr_CurrencyDisplayName().init___T__s_Option("Brazilian cruzeiro (1993\u20131994)", new $c_s_Some().init___O("one")), new $c_Llocales_cldr_CurrencyDisplayName().init___T__s_Option("Brazilian cruzeiros (1993\u20131994)", new $c_s_Some().init___O("other"))]);
  var this$122 = $m_sci_List$();
  var cbf$54 = this$122.ReusableCBFInstance$2;
  var jsx$500 = new $c_Llocales_cldr_NumberCurrency().init___T__sc_Seq__sc_Seq("BRR", jsx$501, $as_sci_List($s_sc_TraversableLike$class__to__sc_TraversableLike__scg_CanBuildFrom__O(xs$54, cbf$54)));

Linking error when using `Duration.compareTo`

Clone reproduction repository and run sbt fastOptJS.

Looks like it could be fixed with an explicit implementation of compareTo in Duration.

Instant has the same problem as well.

LocalDate.now fails if no tzdb in scala.js

LocalDate.now calls Clock.systemDefaultZone. On my machine, it finds that the timezone is Europe/Paris and I end up with an exception:

Uncaught java.time.zone.ZoneRulesException: Unknown time-zone ID: Europe/Paris
    at $p_Ljava_time_zone_ZoneRulesProvider$__getProvider__T__Ljava_time_zone_ZoneRulesProvider (http://localhost:8080/assets/main.js:9479:13)

I can solve it by using tzdb but this is an overkill when all I want is the current year, month and day.

Reduce file size for Scala.js

I am looking forward a way to get the benefits of java.time API and reduce the Scala.js-generated file size at same time. I have started evaluating sbt-tzdb v0.1 for that purpose.

I could save averagely 560KB in size (fullOptJS, no gzipped) in my several projects, by removing timezone DB with zonesFilter := { (z:String) => false}. That is 25%～40% savings for my projects.
(Note: I suppose my projects require no timezone DB, since my code base uses only OffsetDateTime, LocalDate and Duration right now)

I also investigated why some project can save 40%, but other can save only 25%. My observation shows that my projects can save additional 747KB averagely, if DateTimeFormatter usage is eliminated completely. I suppose that there are huge amounts of locales for DateTimeFormatter as similar as timezone DB.

So... it would be great if one can filter locales for DateTimeFormatter in common with timezone DB. (Sorry in advance, in case of my assumption regarding DateTimeFormatter is incorrect)

The below is my observation of file size reduction in my projects.

ZoneId.systemDefault not working

I noticed that ZoneId.systemDefault is not working in javascript, in the jvm it is working fine. My current solution is converting using this:

ZoneId.ofOffset(
    Clock.systemDefaultZone.getZone.getId,
    ZoneOffset.ofTotalSeconds((new Date().getTimezoneOffset()) * -60)

Does it still need implementation?

documentation questions, regarding use on JVM, JS and Native

I was re-implementing a a.pure scala version of banana-rdf, which needs xsd dateTimestamps, and then I realised I need a pure Scala implementation for scalajs. and following links I found your project.

Your documentation states:

The scala-java-time library is currently available for Scala (JVM, version 8 and later) and Scala.js (JavaScript).

Once I noticed that you use the same java.time namespace I got a bit confused, because I wondered if one was meant to override the jvm package, and how one was meant to do that. But @sjrd mentioned that the primary use-case for this lib is not for the jvm... which makes sense, but the sentence above is a bit confusing.

So I guess this is primarily useful for scala-js and Scala-native, right? (Which is actually what I was looking for)

If so that could be made a bit clearer on the documentation page. Either that or one also needs some explanation of how one would make sure one was using your java.time or the JVM one...

Submit scala-java-time to SP (Scala Platform)

With the SP process being announced (https://contributors.scala-lang.org/) I believe that there is a good argument for including scala-java-time into the Scala Platform as it would provide us with an idiomatic cross platform time/date library (and scala-java-time being in the SP would also help drive its adoption). A huge amount of work by @soc was put into making this library, and it would be a shame to see the work go to waste or not live up to its potential.

For the time being, these are the following changes that I would see as needing to be done before we submit (if its chosen to do so)

Rename scala-java-time to something like scala-time, and put the library into a scala.time namespace
Integrate MIMA to ensure binary compatibility
Do any more changes to make the library more idiomatically Scala (if they exist) rather than being just a java.time clone
Resolve any big, outstanding bugs
Add in java converters to seamlessly go from scala.time types to java.time (and vice versa) to make it painless for end users

I'm using this package in project with Scala.js and JVM cross-compilation and it crashes doobie in runtime.

Project is pretty simple and I reproduced it without Scala.js and even without using any org.threeten classes.

import fs2._
import doobie.imports._

object Main extends App {
  val xa = DriverManagerTransactor[Task]("org.postgresql.Driver", "jdbc:postgresql:timefail", "timefail", "timefail")
  case class Item(title: String, createDate: java.sql.Timestamp)

  def insertItem(item: Item): Task[Int] = {
    val sql: Update0 = sql"INSERT INTO items (title, create_date) VALUES (${item.title}, ${item.createDate})".update
    sql.run.transact(xa)
  }

  insertItem(Item("Do somethin", new java.sql.Timestamp(144304323444L))).unsafeRun()
}

As soon as I add scala-java-time into dependencies it starts to crash.

Scala version is 2.12.1, JDK8, I tried it with scala-java-time M7 and M8.
