[snapshot] When setting `override_status_bar` to `true`, the time in screenshot is 10:41 instead of 9:41 about fastlane HOT 1 OPEN

Sorry, this is a duplicate of #21464

However, I figured it out and have a work-around.

Analysis

When using override_status_bar true, the console log shows the automatically generated arguments:

$ xcrun simctl status_bar 463A8557-2F51-432A-A880-7EA671F20805 override --time 2007-01-09T09:41:00+01:00 --dataNetwork wifi --wifiMode active --wifiBars 3 --cellularMode active --operatorName '' --cellularBars 4 --batteryState charged --batteryLevel 100 &> /dev/null

When adding override_status_bar_arguments "--wifiBars 3", the console log shows:

$ xcrun simctl status_bar 4CD9AAB8-AAF8-461D-B077-7815623A2436 override --wifiBars 3 &> /dev/null

The reason why the latter worked, was because my Simulator was already started with Simulator Status Magic enabled.
Using a brand new Simulator, doesn't show the "9:41", but the current time. This clarifies 1 observation.

So the root cause is in the ISO time stamp for parameter --time: 2007-01-09T09:41:00+01:00.
The time zone +01:00 is wrong, since I'm at CEST which has Daylight Saving enabled, so it's currently +02:00.

Work-around

When manually changing the timezone in the arguments in the Snapfile the correct time is displayed in the screenshots:

override_status_bar_arguments "--time 2007-01-09T09:41:00+02:00 --dataNetwork wifi --wifiMode active --wifiBars 3 --cellularMode active --operatorName '' --cellularBars 4 --batteryState charged --batteryLevel 100"

However, when running Snapshot in winter, it will display the wrong time. Hence made the time zone offset dynamically in the Snapfile with some Ruby code:

require 'active_support/all'    # For `Time.now.formatted_offset()`

devices([
    "iPhone 12 Pro",
    ])

# Get current timezone offset:
timezone_offset = Time.now.formatted_offset(true)
puts("timezone_offset = #{timezone_offset}")               # Optional, to write to Console output

# Override status bar and override arguments incl. timezone offset, as by default it goes wrong with Daylight Saving Time (e.g. shows "10:41" instead of "9:41", see: https://github.com/fastlane/fastlane/issues/22026 )
override_status_bar true
override_status_bar_arguments "--time 2007-01-09T09:41:00#{timezone_offset} --dataNetwork wifi --wifiMode active --wifiBars 3 --cellularMode active --operatorName '' --cellularBars 4 --batteryState charged --batteryLevel 100"    # For a list of commands, type the following in Terminal: xcrun simctl status_bar --help

Solution

To resolve this in code, the Time object should get the proper time zone information, see:

from fastlane.
