UTC = Universal Time.

You can convert your current local time to UTC by 

DateTime dt= DateTime.UtcNow;

or convert a specified date/time by

TimeZoneInfo myTZInfo = TimeZoneInfo.FindSystemTimeZoneById("AUS Eastern Standard Time");

// DateTime.SpecifyKind(Convert.ToDateTime("04:35 AM"), DateTimeKind.Unspecified), myTZInfo) tells whether you are conetring a local time or UTC, you can always leave it as unspecified

TimeZoneInfo.ConvertTimeToUtc(DateTime.SpecifyKind(Convert.ToDateTime("2015-01-06 14:00:00.000"), DateTimeKind.Unspecified), myTZInfo).ToString("hh:mm tt")

you can get all time zone ids by==>

ReadOnlyCollection<TimeZoneInfo>  tzc= TimeZoneInfo.GetSystemTimeZones();

I would think they're both the same - according to Wikipedia, UTC is Coordinated *Universal* Time.

.NET supports UTC through a number of function on the DateTime struct. E.g. there is are functions like DateTime.ToUniversalTime (and DateTime.ToLocalTime to convert back, of course) or DateTime.UtcNow available.

No difference. DateTime.UtcNow gives you the current time in UTC. The Timezone class has functions to convert to and from UTC date/time to date/time in any timezone.
