FAQ.aspx
If you want to record local times in such a way that they can be compared
accurately accross time zones and independently of DST, you must record the
local time zone offset alongside each instance. Use
TimeZone.CurrentTimeZone.GetUtcOffset(DateTime) to record this for a given
point in time. Unlike Win32, this calculation can calculate a different
offset in a past and future.
What do you mean by FCL support? If you mean conversion between arbitrary
time zones, that is not currently present in the Framework, but may be in a
future version.
