How do I get a specific TIME_ZONE_INFORMATION struct in Win32?

Question

The Win32 GetTimeZoneInformation function returns your systems local time zone as set up in the control panel. How do I get another specific time zone? Is there a call that does this?

Answer 1

According to this the information for the different timezones is stored in the registry, so you will have to retrieve the information from there and populate the TIME_ZONE_INFORMATION struct yourself.

Quote from the msdn article

Remarks

Settings for each time zone are stored in the following registry key:

HKEY_LOCAL_MACHINE
     SOFTWARE
          Microsoft
               Windows NT
                    CurrentVersion
                         Time Zones
                              time_zone_name
