你可以使用下面的代码，如果你知道哪些本地时区你靶向

DateTime timeUtc = DateTime.UtcNow; 
    try 
    { 
    TimeZoneInfo cstZone = TimeZoneInfo.FindSystemTimeZoneById("Central Standard Time"); 
    DateTime cstTime = TimeZoneInfo.ConvertTimeFromUtc(timeUtc, cstZone); 
    Console.WriteLine("The date and time are {0} {1}.", 
       cstTime, 
       cstZone.IsDaylightSavingTime(cstTime) ? 
         cstZone.DaylightName : cstZone.StandardName); 
    } 
    catch (TimeZoneNotFoundException) 
    { 
    Console.WriteLine("The registry does not define the Central Standard Time zone."); 
    }       
    catch (InvalidTimeZoneException) 
    { 
    Console.WriteLine("Registry data on the Central STandard Time zone has been corrupted."); 
    }
