DWORD GetDynamicTimeZoneInformation( [out] PDYNAMIC_TIME_ZONE_INFORMATION pTimeZoneInformation );
A pointer to a DYNAMIC_TIME_ZONE_INFORMATION structure.
If the function succeeds, it returns one of the following values.
||Daylight saving time is not used in the current time zone, because there are no transition dates.|
||The system is operating in the range covered by the StandardDate member of the DYNAMIC_TIME_ZONE_INFORMATION structure.|
||The system is operating in the range covered by the DaylightDate member of the DYNAMIC_TIME_ZONE_INFORMATION structure.|
If the function fails, it returns TIME_ZONE_ID_INVALID. To get extended error information, call GetLastError.
The StandardName and DaylightName members of the resultant DYNAMIC_TIME_ZONE_INFORMATION structure are localized according to the current user default UI language.
