Windows Phone users can set the time zone via the Settings -> Datetime Form in the Windows Phone.
By default , the time zone was “UTC +05:30 Chennai,Kolkatta,Mumbai,New Delhi” on my Windows Phone that was set via the “Set automatically” option.
How to Retrieve the TimeZone Programatically in Windows Phone
If you want to retreive this information (Timezone) , you can use the TimeZoneInfo.Local property that is defined in the System.Security NameSpace.
TimeZoneInfo.Local includes the properties StandardName and DisplayName to display the time zone.
txtTimeZone.Text = TimeZoneInfo.Local.StandardName;
The StandardName will display the complete text like “UTC +05:30 Chennai,Kolkatta,Mumbai,New Delhi”
txtTimeZone.Text = TimeZoneInfo.Local.DisplayName;
The DisplayName will in turn display the Zone Name like “India Standard Time”.
