Changing the time zone breaks the system #4782

Hi,

I changed the time zone value for the admin user for the default tenant. Then I clicked on the button to refresh the app and it crashed. I was not able to login again until I deleted the time zone setting for the admin user at the AbpSettings table.

Prior to delete the time zone setting at the AbpSettings table I inspected the Audit Logs and found the following exception: System.Exception: Unable to map America/Tijuana to iana timezone. at Abp.Timing.Timezone.TimezoneHelper.WindowsToIana(String windowsTimezoneId) at Abp.Web.Configuration.AbpUserConfigurationBuilder.

This exception is happening at the AbpUserConfigurationController.GetAll method

I realized that the time zone value stored at the AbpSettings table was "America/Tijuana" which corresponds to the IANA time zone format and so when calling the WindowsToIana method it fails cause "America/Tijuana' is not a valid Windows Standard time zone value.

So, I'm wondering if this is a bug in the system or a missing configuration.

Please advice! Thanks!

    Hi @softcial,

    What is your AspNet Zero version ? This problem must be fixed with <a class="postlink" href="https://github.com/aspnetzero/aspnet-zero-core/issues/667">https://github.com/aspnetzero/aspnet-ze ... issues/667</a>.

    I'm using version 5.0.0

    Do I have to replace the library you are using by the one specified in the provided link?

    You mean that I have to update to ASP.NET zero 5.1, right?

    Unfortunately, updating the system to the 5.1.0 version didn't work. The TimingService.GetTimeZones method continues returning IANA time zone values as show below: "result": { "items": [ { "name": "Default [UTC]", "value": "" }, { "name": "GMT-12:00", "value": "Etc/GMT+12" }, { "name": "GMT-11:00", "value": "Etc/GMT+11" }, { "name": "Hawaii-Aleutian Standard Time", "value": "America/Adak" }, { "name": "Hawaii-Aleutian Standard Time", "value": "Pacific/Honolulu" }, { "name": "Marquesas Time", "value": "Pacific/Marquesas" }, { "name": "Alaska Standard Time", "value": "America/Anchorage" }, { "name": "GMT-09:00", "value": "Etc/GMT+9" }, { "name": "Pacific Standard Time", "value": "America/Tijuana" }, { "name": "Pacific Standard Time", "value": "America/Los_Angeles" }, ...

    I modified the code as follows (changing Id to StandardName as the entry for the "value" property) ...

    public List<NameValueDto> GetWindowsTimezones() { return TZConvert.KnownWindowsTimeZoneIds.Select(TZConvert.GetTimeZoneInfo) .OrderBy(tz => tz.BaseUtcOffset) .Select(tz => new NameValueDto { Value = tz.StandardName,//tz.Id, Name = tz.DisplayName }).ToList(); }

    ... obtaining the following output from the TimingService.GetTimeZones method: { "result": { "items": [ { "name": "Default [UTC]", "value": "" }, { "name": "GMT-12:00", "value": "GMT-12:00" }, { "name": "GMT-11:00", "value": "GMT-11:00" }, { "name": "Hawaii-Aleutian Standard Time", "value": "Hawaii-Aleutian Standard Time" }, { "name": "Hawaii-Aleutian Standard Time", "value": "Hawaii-Aleutian Standard Time" }, { "name": "Marquesas Time", "value": "Marquesas Time" }, { "name": "Alaska Standard Time", "value": "Alaska Standard Time" }, { "name": "GMT-09:00", "value": "GMT-09:00" }, ...

    and now I'm getting the following exception when setting any user time zone property: System.TimeZoneNotFoundException: The time zone ID 'Central Standard Time' was not found on the local computer. ---> System.IO.FileNotFoundException: Could not find file '/usr/share/zoneinfo/Central Standard Time'.

    That is because "Central Standard Time" does not exist as a time zone in Ubuntu (the OS for the hosting server).

    So, I think that the system must be updated in order to properly handle IANA time zones for Unix based operating systems. Any thoughts? Thanks!

    Can you try the fix in this issue <a class="postlink" href="https://github.com/aspnetzero/aspnet-zero-core/issues/903">https://github.com/aspnetzero/aspnet-ze ... issues/903</a> ?

    By they way, the latest version of GetWindowsTimezones method should be like below;

    public List<NameValueDto> GetWindowsTimezones()
{
	return TimezoneHelper.GetWindowsTimeZoneInfos().OrderBy(tz => tz.BaseUtcOffset)
		.Select(tz => new NameValueDto
		{
			Value = tz.Id,
			Name = tz.DisplayName
		}).ToList();
}
