Question

How to get regional timezone on Compact Framework and then convert UTC date to local date?

Answer 1

P/Invoke GetTimeZoneInformation to get the current timezone biases, then use those to offset the UTC time.

Alternately you could use the DateTimeHelper.GetTimezoneInformation call in the SDF.

Answer 2

The DateTime.ToLocalTime() method is available on CF, no need to jump through hoops. Do make sure to use a DateTime constructor that takes a DateTimeKind argument so you can tell it that it's a UTC time, if necessary.
