TimeZoneInfo.GetSystemTimeZones().Count gives 0 for unity android app

Question

TimeZoneInfo.GetSystemTimeZones().Count gives 0 for unity android app, is there any permission required from android side to get TimeZone data?

Debug.LogError("GetSystemTimeZones... " + System.TimeZoneInfo.GetSystemTimeZones().Count);

Output : GetSystemTimeZones... 0

There is a Unity Issue on the matter, it seems that it was not yet fixed but on the comments you can find more about it and probably a workaround: https://issuetracker.unity3d.com/issues/win-system-dot-timezoneinfo-does-not-return-any-time-zones — Vitor Figueredo, Jan 22 '20 at 13:06
@VitorFigueredo this only happens in android app where as **iOS** version of same app works fine. — SagarAnjWebTech, Jan 22 '20 at 13:12

I think this method always returns 0 on Android. Reading on the Documentation for TimeZoneInfo:

The GetSystemTimeZones method retrieves all available time zone information from the subkeys of the registry's HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Time Zones key on Windows systems and from the ICU Library on Linux and macOS.

As you can see, Android is not mentioned.

based on the documentation it is supposed to return 0 in android! but I saw some people do a workaround to solve this problem. it goes as follow: you can create a jar with Android Studio and get the timezones you need there and then create a C# script to access that jar file. here you can find a toturial on how to do it.

although in this scenario there is a drawback, you can only pass Strings with this solution.
