Description arscroggin@sep.com 2015-01-12 14:53:16 UTC
When I try to convert a DateTime to the same time zone, it does not work.  It should come back with the same time, but it does not.  I works on Windows .NET, but not on Xamarin.Android.

var dt = new DateTime(2015,1,12,13,30,0,DateTimeKind.Unspecified);

var sameDateTime = TimeZoneInfo.ConvertTime( dt, TimeZoneInfo.Utc, TimeZoneInfo.Utc )

Assert.That(dt, Is.EqualTo(sameDateTime), "Should be the same");

It doesn't have to be the same timezone.  I did a second test using a local time zone and converted it to Utc.  The time was also wrong in that case.

I am using Xamarin Android 4.20

I have checked this issue with creating Console, iOS and Android project and observed that TimeZoneInfo.ConvertTime is working fine with Console and iOS project as well but fails with Android Project..
