Using the - format for newer versions of strftime doesn't output correctly. Since there is a dependency on the system's strftime version, it seems like it could support both (and just always fall back to %m and %d. Obviously using %e instead of %-d is an option for day, but there isn't a great alternative for month.

Consider this example:

"Ends #{ local_time(auction.ends_at, '%m/%d at %l:%M%P %Z') }".html_safe

yields the correct date:

Ends 09/24 at 2:13pm CDT

Meanwhile,

"Ends #{ local_time(auction.ends_at, '%-m/%-d at %l:%M%P %Z') }".html_safe

yields this incorrectly:

Ends %-m/%-d at 2:13pm CDT

which should yield:

Ends 9/24 at 2:13pm CDT

I have a non-english Rails app which use local_time gem:

<%= local_time_ago(obj.created_at) %>

I am trying to localize it. On the client side, everything is working just fine. The text shows in my custom language. But on the first load of the page I get the english text (I guess this is the server side text?). How to set the locale of local_time gem on server side? I have already set config.i18n.default_locale

I have been using local_time to convert servertime to client local time. However now I am using datatables and to sort date/time columns. I have to use date-moment.js plugin of Datatables which uses moment.js to handle date conversions.

My problem is: the local_time's view helper is wrapping the date with < time > tag like this

<time data-format="%B %e, %Y %l:%M%P"
      data-local="time"
      datetime="2013-11-27T23:43:22Z"
      title="November 27, 2013 6:43pm EDT"
      data-localized="true">November 27, 2013 6:43pm</time>

The wrapping thing is creating problem for moment.js to get the actual date-time as it expects. I need it to convert the date-time but not wrap with <time> tag. Is it possible. If yes How?

Hi I just stumbled upon local_time and I am wanting to use it for a playlist, some 100 timestamps spread out over a whole day. Presenting the playlist to our listeners in their local timezone ...

However I am supplying a strange timestamp that I am getting from my JSON api.
0312201217:52:09 %d%m%Y%H:%M:%S

When I supply following timestamp local_time(time, format: '%d%m%Y%H:%M:%S' )

I get an error 'argument out of range'. I could not find this error message anywhere in your code, maybe you have hint how to fix this.

BTW if my timestamps already come from a certain timezone, could I supply a timezone other than UTC?

Thanks alot for the engine!

When using local_time in a windows browser it does not display the timezone.

local_time(datetime,'%l:%M %p (%Z)')

When doing this to display the time %Z returns nothing on windows.

On unix it correctly shows code.

I believe this is because on unix it formats the time as : Tue Jun 24 2014 13:19:42 GMT-0600 (EDT)

However on windows it is : Tue Jun 24 2014 13:19:42 GMT-0400 (Eastern Daylight Time)

This piece seems to be broken:
`parseTimeZone = (time) ->
string = time.toString()

Sun Aug 30 2015 10:22:57 GMT-0400 (NAME)

if name = string.match(/(([\w\s]+))$/)?[1]
if /\s/.test(name)
# Sun Aug 30 2015 10:22:57 GMT-0400 (Eastern Daylight Time)
name.match(/\b(\w)/g).join("")
else
# Sun Aug 30 2015 10:22:57 GMT-0400 (EDT)
name`

Hi,

Environment:

Ruby 2.4.3 and Rails 5.1.4
Ubuntu 14.04

I added <%= local_time(time) %> at app/views/layouts/application.html.erb and getting below error

undefined local variable or method `time' for #<#<Class:0x00007f10b14940d0>:0x00007f10b14763f0>
Did you mean?  timer

How to fix it ?

Thanks.

This is more of a feature request than a bug, but %-d isn't supported, while %d is.

Recreate with the following:

LocalTime.strftime(new Date, '%a %b %d %l:%M %p %Z')
LocalTime.strftime(new Date, '%a %b %-d %l:%M %p %Z')

Output:

"Tue Sep 01 12:38 PM CDT"
"Tue Sep %-d 12:38 PM CDT"

Expected Output

"Tue Sep 01 12:38 PM CDT"
"Tue Sep 1 12:38 PM CDT"

From the ruby DateTime doc:

    %d - Day of the month, zero-padded (01..31)
            %-d  no-padded (1..31)

If I can find where this is happening when I'm free, I'll take a stab at it myself.

How to use either local_time or local_relative_time helper in emails?

If I have a DateTime object (datetime = DateTime.parse('5/8/10 8:53')), and strftime it with non-padded indicators (like %-e and %-I), in ruby-land, it all renders correctly

Time.now.utc.strftime('%b %-e, %Y %-l:%M %p') # => "Aug 5, 2010 8:53 AM"

and it works great with local_time

local_time(Time.now.utc, Time.now.utc) 
#=> <time datetime=\"2010-08-05T08:53:00+00:00\" data-local=\"time\" data-format=\"%b %-e, %Y %-l:%M %p\">Aug 5, 2010 8:53 AM</time>

But the javascript seems to lack compatibility

<time datetime="2010-8-5T08:53:00Z" data-local="time" data-format="%b %-e, %Y %-l:%M %p" title="August 8, 2010 at 8:53am EST" data-localized="true">Aug %-e, 2010 %-l:53 AM</time>

It ultimately renders Aug %-e, 2010 %-l:53 AM, which is not expected.

Hi,

Has anybody done the integration of local_time with Analog or Digital clocks ?

http://www.webdeveloperjuice.com/2010/02/07/7-wonderful-analog-and-digital-clocks-using-css-and-javascript/

Thanks.

The use of element.innerText = means this doesnt work with FF - I believe element.textContent = should work

Hi,
I'm using local time like this:
<td><%= local_time(node.last_seen) %></td>
And when I'm opening the page I see non-converted time:
<time datetime="2017-03-30T17:36:39Z" data-local="time" data-format="%B %e, %Y %l:%M%P">March 30, 2017 5:36pm</time>
After I'm pressing F5 to refresh the page:
<time datetime="2017-03-30T17:36:39Z" data-local="time" data-format="%B %e, %Y %l:%M%P" title="March 30, 2017 at 8:36pm RST" data-localized="true">March 30, 2017 8:36pm</time>

So, it's smells like some kind of caching. Maybe I'm cooking gem in wrong way?

Thank you.

For my purpose is important that administrator of the app will see last user's timezone ... Is it possible to get user's timezone somehow into controller and store in users profile ... ?
Very essencital for me ... O:)
THX!!

#time_ago_in_words aka #distance_of_time_in_words (http://api.rubyonrails.org/classes/ActionView/Helpers/DateHelper.html#method-i-distance_of_time_in_words) always uses a unit of time. 20 seconds, 5 weeks, 8 years, etc.

#local_time_ago transitions from a description to a date with age.

# Today: "Saved 5 hours ago"
# Yesterday: "Saved yesterday at 8:15am"
# This week: "Saved Thursday at 8:15am"
# Older: "Saved on Dec 15"

For example, whereas the README seems to imply "on" will only be added to dates older than a week when using the Time Ago Helper, the gem is really posting things like "on 2 minutes ago" instead of "2 minutes ago."

When LocalTime is loaded via an async script tag, like this:

<script src="/assets/application-######.js" async></script>

Then there is a possibility that the browser will load the document and fire the DOMContentLoaded event before parsing and executing the LocalTime JavaScript. This is 100% reproducible in my current project using Firefox 46.0.1 and Safari Technical Preview v5.

LocalTime depends on receiving the DOMContentLoaded event in order to initialize. Without it, its domLoaded variable is permanently set to false, which essentially disables the entire library.

This is a common problem and is well documented (and answered) in this Stack Overflow question: http://stackoverflow.com/questions/9237044/async-loaded-scripts-with-domcontentloaded-or-load-event-handlers-not-being-call .

The solution, it seems, is to check if (document.readyState !== "loading") at parse time. If this evaluates to true, then LocalTime should initialize immediately instead of waiting for a DOMContentLoaded event that will never arrive.

I can open a PR to make this change, but since JavaScript is not my strong suit, I thought I would get feedback via a bug report first. Is this a reasonable fix?

As it stands, the workaround in my particular project will be to remove async from my script tag.

For example, I would like to be able to specified "%-m" instead of "%m" to display 2 instead of 02 (http://apidock.com/ruby/DateTime/strftime).

I'd be willing to add this support and the relevant tests if there'd be any desire to have this in the gem.

The time in my app is incorrect when reloading the page, but changes to the correct time at some point later (usually within a split second, but sometimes it takes a few). I've followed everything in the docs to the tee, and I have LocalTime.run(); in my Action Cable function as suggested in this answer.

How can I make this work so that the seams are not showing?

Is it possible that the local_time gem may confuse some timezones - for example Arabia Standard Time (UTC+3) and Atlantic Standard Time (UTC-4) are both abbreviated to AST.

See AgileVentures/WebsiteOne#1097 for more details.

Any idea if there is a quick fix for this sort of thing?

I18n.t("time.formats.#{format}"), I18n.t("date.formats.#{format}"), Time::DATE_FORMATS[format], and Date::DATE_FORMATS[format] will be scanned (in that order) for your format.

According to this behavior a Date object will be formatted with time formats.

en:
  time:
    formats:
      default: '%H'
  date:
    formats:
      default: '%a'

<%= local_date(Date.today, format: :default) %> # will be formatted as time

Hi,

Is there a timer functionality available ?

I could not find the timer command.

Let me know how to implement it.

Thanks.

I'm having trouble getting this to work on ie8 which does not have addEventListener

Do you have recommendations for a shim or polyfill that will work with this?

I tried a couple unsuccessfully....

With <%= local_time_ago(time) %>, I could see "an hour ago", but I would like to see "an hour 2 min ago".

How should I achieve it ?

Thanks.

my requirement of adding this from js , so how to use local_time_ago in js file and in controllers?

In my view I have the line:

<%= local_time_ago(note.updated_at) %>

This correctly displays something like "22 minutes ago"

However, if I then click a link

<%= link_to "Home", root_path %>

that reloads the same page it suddenly changes to something like "December 12, 2013 6:58am"

If I wait a minute it updates and switches back to the nice form like "24 minutes ago"

Any way to prevent this intermediate state? Am I doing something wrong.

This is using 0.2.0 version of the gem. It happens both with the latest Chrome Version 31.0.1650.63 and latest Safari Version 7.0 (9537.71)

Hi I get this in my JS error logs:

An invalid or illegal selector was specified (selector: 'time[data-local]:not([data-localized])' error: Invalid selectors: time[data-local]:not([data-localized]))

https://github.com/basecamp/local_time/blob/master/app/assets/javascripts/local_time.js.coffee#L196

The browser is mobile safari 5.0.2.

if cached page is more than a week old, <time> will remain blank even after LocalTime.run()

So either we introduce weekday-or-date (or fix weekday to behave like that)

when "weekday-or-date"
  relativeWeekday(time) ? relativeDate(time)

Calling $(document).trigger('time:elapse'); doesn't seem to replace times added via ajax.

I'm building a blog where I want readers to be able to add comments via ajax, but when I create a comment, the utc time of the comment is shown and isn't replaced by the relative time.

My comments/create.js.erb view looks like this:

var $comment = $("<%= j render(@comment) %>");

$('#new_comment').slideUp(function () {
  $comment.replaceAll(this).hide().slideDown();
  $(document).trigger('time:elapse');
});

Hello!

The source code link from https://rubygems.org/gems/local_time

needs to update from https://github.com/37signals/local_time to https://github.com/basecamp/local_time/.

Thanks!

Hello,

For some reason, local_time is showing time stamps in the future by 4 hours. My application.rb does not change the default time zone from UTC, however there is a before_action that sets the Time.zone to the current user's time zone, which in my case is "Eastern Time (US & Canada)".

Anywhere I render a date without using local_time, the time zone conversion is accurate, however when I substitute with local_time, I'm jumped ahead by 4 hours. Can you help point me in the right direction?

Sorry I haven't been able to figure this out... Still learning how to navigate through code ⛵️

In my application, no user time zone is set. All times are in UTC.

record.created_at renders as
"2015-01-08 18:25:41 UTC"

and when used with <%= local_time(record.created_at) %>

it renders as
January 8, 2015 6:09pm

which ultimately displays as "6:009PM" even though it is "10:09AM" where I am (PST)

It seems the time is just staying in UTC.

I had hoped that UTC would display in the zone of the browser automatically. Perhaps that is a configuration option.

This is my code:
<%= local_time(conversation.updated_at, '%l:%m %p') %>

This produces:
<time datetime="2017-05-22T23:00:35Z" data-local="time" data-format="%l:%m %p" title="May 22, 2017 at 4:00pm PDT" data-localized="true">4:05 PM</time>

Why does it say "4:05" in the actual text that displays, in spite of the fact that both the time stamp and even the title both clearly end in ":00"?

This is bizarre, and I haven't the foggiest idea where to even look... it's doing this with many different times, too (:24, :23, :39, etc.). It's not the javascript doing it... when I look at what comes back from my server, the "HTML time" ends in :05, as well:
<time datetime="2017-05-22T23:00:35Z" data-local="time" data-format="%l:%m %p">11:05 PM</time>

Anyone have any help for me?

Are there any plans to add i18n support @javan?
We would love to use this plugin but our side serves english and german content.
It look like the only similar plugin with i18n support is http://timeago.yarp.com/.

I have installed gem 'local_time' in my application and require 'local_time' in application.js properly.
But, when i try to use local_time helper. Its showing error that local_time is not defined.

= local_time(User.first.created_at)
=>
undefined method `local_time' for #<#<Class:......>

Using local_time(datetime, :long) doesnt translates correctly the month (shows on default en language), long format is defined as '%d de %B de %Y' as is on language es-ES. (Using l(datetime) shows the date correctly translated, but not in local time as aims this gem).

I'm in the process of converting a large Rails project over to Webpacker and we have local_time as a dependency. Hence, it'd be great to make the javascript inthis project available via NPM. Looks like this would require a release step to build JS from the CoffeeScript source, make compatible with requireJS/ES6-modules, and coordinate publishing to Rubygems and NPM, or perhaps having a separate repo altogether.

Is this something you'd consider for this project?

It would eliminate the coffee_script dependency, which is currently required.

Hi, have you thought a way to translate in javascript? I could just re-write your class code in another language but that is not cool....

Maybe in the helper tag add the translations as a hash with fallback as the current ones? There are not too many translations in that Class anyway:

"#{ago} ago"
"#{day} at #{@formatTime()}"
"on #{@formatDate()}"
"a second"
"#{sec} seconds"
"a minute"
"#{min} minutes"
"an hour"
"#{hr} hours"
"today"
"yesterday"

When using %Z format specifier, some abbreviations are not the same as in abbreviation tables such as: https://www.timeanddate.com/time/zones/.

For instance, Alaska Daylight Time should be abbreviated as AKDT and instead is showing as ADT which is Atlantic Daylight time.

Gem version used: 2.0.1

Steps to reproduce:

1. Include <%= local_time(Time.now, format: "%I:%M %p %Z") %> in a test view.
2. Force a geolocation using the browser's dev tools. Use Location name: Anchorage, Lat: 61.2181, Long: -149.9003, Timezone ID: America/Anchorage (In Chrome this is done by opening Dev tools and selecting (settings)>>more tools >> sensors, and then click on add location)

Not sure if this is a known issue (didn't find anything):

= local_time(@batch.scheduled_for, "%Y/%m/%d %H:%M %Z")

Works in Chrome:

but not in Firefox:

Any idea what the best approach is to localize this gem - ideally using Rails i18n API? (besides simply replacing strings in the gem by a different language).

I'm having a problem displaying the correct time when I put local_time inside of Bootstrap's tooltip. Formatting works, but the time remains UTC time instead of PDT time.

<% @product.users.each do |user| %>
  <% if user.active %>
    <img src="<%= user.image %>" class="user-image" data-toggle="tooltip" data-placement="bottom" data-html="true" title='Last Logged in: <br> <%= local_time(user.updated_at) %>' />
    <% end %>
 <% end %>

Would display

Last Logged In:
December 18, 2015 3:53am

instead of

Last Logged In:
December 18, 2015 7:53pm

So it does format the date, it just doesn't change the date to my local time zone like I wanted it to.

Is it possible to access the localized time in Javascript?

In this example from the docs:
LocalTime.strftime(new Date( "Jun 24 2014 13:19:42" ), "%l:%M%P")

The timezone offset has not been applied, and I don't see how to do so.

Hey guys, thanks for the great gem.

I just upgraded to Rails 5.0.3 and local_time 2.0 and I get this error:

ActionView::Template::Error (couldn't find file 'local_time' with type 'application/javascript'
Checked in these paths:
....
....
  /Users/Ahmad/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/local_time-2.0.0/app/assets/javascripts

It seems to have installed the gem but can't find it. Reverting back to 1.0.3 the error goes away.

Thanks

If a time passed to local_time_ago happens to be nil, it will throw an error:

undefined method `to_time' for nil:NilClass

would it be possible to have local_time_ago handle this gracefully by returning nil or ''?

The support for time formats works well, but it doesn't seem to translate the names of the months, etc.

I18n.with_locale(:fr) do
  <%= local_time model.from, :date %> 
  # => "Saturday 28 May 2016" instead of "Samedi 28 Mai 2016"
end

I want to replace Jquery-time-ago to local_time but the only reason that I didn't is that i can't use I18n for local_time_ago helper.
Thank you.

hi
any way to modify the time to show "time"(at 12:32 am) instead of "hours" (less than 5 hrs) for less than 1 day
also, to include time if on other day of year or another year?
thnx

Sometimes the gem takes maybe more than a minute to convert the text using the local_time_ago helper. Anyone aware about this and/or knows a solution? I'm also using turbolinks, if that can be an issue.
