Message:

[WIN] Use GetTimeZoneInformation() for getting the timezone name

Reviewed by Ryosuke Niwa.

The MS CRT implementation of strftime calls the same functions in the background.
Using them directly avoids the overhead of parsing the format string and removes
the dependency on strftime() for WinCE where this function does not exist.
