Convert UTC to IST using C#

Try This:

DateTime utcdate = DateTime.ParseExact("6/15/2014 12:00:00 AM", "M/dd/yyyy 
                                       h:mm:ss tt",CultureInfo.InvariantCulture);
var istdate = TimeZoneInfo.ConvertTimeFromUtc(utcdate,
TimeZoneInfo.FindSystemTimeZoneById("India Standard Time"));

I'm getting output :

6/15/2014 5:30:00 AM

You could also try:

        DateTime utc = TimeZoneInfo.ConvertTimeToUtc(new DateTime(2014, 6, 16, 2, 0, 0));
        DateTime temp = new DateTime(utc.Ticks, DateTimeKind.Utc);
        DateTime ist = TimeZoneInfo.ConvertTimeFromUtc(temp, TimeZoneInfo.FindSystemTimeZoneById("India Standard Time"));
