Convert date time to format “dd.MM.yyyy” from another time zone to +2

Question

I want to convert this format:

2012-08-09T07:48:16+02:00

2012-01-17T17:49:05+01:00

2012-01-17T17:49:05-05:00

to " dd.MM.yyyy " in time zone UTC+02:00

Answer 1

Check this way:

    var dt = DateTime.Parse("2012-08-09T07:48:16+02:00");
    var newDt = TimeZoneInfo.ConvertTime(dt, TimeZoneInfo.FindSystemTimeZoneById("FLE Standard Time"));
    Console.WriteLine(newDt.ToString("dd.MM.yyyy"));

By the way, UTC+02:00 it's not name of timezone, real time will depend on country and daylight saving rules.

Answer 2

Try this way

TimeZoneInfo.ConvertTimeBySystemTimeZoneId(DateTime.Now, "New Zealand Standard Time", "UTC")
