Windows provides facilities for that:

GetSystemTime() as UTC:

Convert UTC Time to other Timezones:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms724949%28v=vs.85%29.aspx

Since you're not in C++ it will require parsing out the data in complex ways with SUBSTR(), BINTOC() and CTOBIN(), but it is doable.

BOOL WINAPI SystemTimeToTzSpecificLocalTime(
  _In_opt_  LPTIME_ZONE_INFORMATION lpTimeZone,
  _In_      LPSYSTEMTIME lpUniversalTime,
  _Out_     LPSYSTEMTIME lpLocalTime
);

You could use this to pre-populate your memory block, and then just change the portions you need:

DWORD WINAPI GetTimeZoneInformation(
  _Out_  LPTIME_ZONE_INFORMATION lpTimeZoneInformation
);
