Hi

I have this line to get all the timezones

 Dictionary<string, TimeZoneInfo> storeZoneName = TimeZoneInfo.GetSystemTimeZones().ToDictionary(z => z.DisplayName);

They are different. Same line of code but one is GMT and one is UTC. How can I force it to be always the same?

Also I want to have a default choice of "UTC" but I am not sure what the diff is between this

(UTC-11:00) Coordinated Universal Time-11

and this

  (UTC-02:00) Coordinated Universal Time-02
