Hi,

You have to update your ABP packages.
In ABP Abp.Timing.Timezone.TimezoneHelper class fixed.
And in AspNet Zero TimingAppService and TimeZoneService is fixed.

See the GitHub issue: <a class="postlink" href="https://github.com/aspnetboilerplate/aspnetboilerplate/issues/3223">https://github.com/aspnetboilerplate/as ... ssues/3223</a>

Could you please be specific about the packages to be updated and the version.

I upgraded TimeZoneCoverter to 2.3.2, as mentioned in the github issue, but it did not resolve the error I am getting.

@cpadmin,

Updating nuget packages (all ABP packages to 3.5 and TimeZoneCoverter to 2.3.2) might not solve your problem.
Can you share your existing ABP nuget package version and AspNet Zero version ?

Thanks.

Hi,

ABP version: 3.4.0
AspNet Zero version: 5.1.0

Then, probably I think your problem is related to <a class="postlink" href="https://github.com/aspnetzero/aspnet-zero-core/issues/903">https://github.com/aspnetzero/aspnet-ze ... issues/903</a>.
Can you try to apply the fix ?

Hi,
By looking into the resolution of the issue, mentioned by you, I can deduce that the definition of the GetWindowsTimezones method, in my version of ABP, is up-to-date:

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

I can also see that the lodger of the thread was able to retrieve Timezones even when he was using -version 5.0.0. Then what could possibly go wrong in my version of ABP and ASP.NET Zero?

It has to do something with TimingAppService as I can see from the Audit Log.

The log says:

System.InvalidTimeZoneException: "Aleutian Standard Time" was not recognized as a valid IANA time zone name, or has no equivalant Windows time zone.

What to do now?

Hi @cpadmin,

Can you share your project via email ?
It will be easier to check it like that.

Thanks.

I am very sorry but I cannot share the project with you as it is client's property. But if you want I can share you the Audit logs related to Timezone.

No problem. Can you share TimingAppService.cs and TimeZoneService.cs ?

Hi,

In TimingAppService.cs, there is a line;

var defaultTimezone = TimeZoneInfo.FindSystemTimeZoneById(defaultTimezoneId);

You need to change it to;

var defaultTimezone = _timeZoneService.FindTimeZoneById(defaultTimezoneId);

It says: 'ITimeZoneService' does not contain a definition for 'FindTimeZoneById'

Even after making the given changes I am still getting the same error:
System.InvalidTimeZoneException: "Aleutian Standard Time" was not recognized as a valid IANA time zone name, or has no equivalant Windows time zone.

@cpadmin, are there any records on your AbpSettings table with the value of "Aleutian Standard Time" ?
If not, we can arrange a remote meeting to solve your problem for the next week.
