GetTimeZoneInformation info  Overview  Group

The GetTimeZoneInformation function retrieves the current time-zone parameters. These parameters control the translations between Coordinated Universal Time (UTC) and local time.

DWORD GetTimeZoneInformation(

    LPTIME_ZONE_INFORMATION lpTimeZoneInformation 

// address of time-zone settings

   );

Parameters

lpTimeZoneInformation
Points to a TIME_ZONE_INFORMATION structure to receive the current time-zone parameters.

Return Values

If the function succeeds, the return value is one of the following values:

Value

Meaning

TIME_ZONE_ID_UNKNOWN

The operating system cannot determine the current time zone. This is usually because a previous call to the SetTimeZoneInformation function supplied only the bias (and no transition dates). Windows NT: This value is also returned if daylight savings time is not used in the current time zone (StandardBias equals DaylightBias).

TIME_ZONE_ID_STANDARD

The operating system is operating in the range covered by the StandardDate member of the TIME_ZONE_INFORMATION structure. Windows 95: This value is also returned if daylight savings time is not used in the current time zone (StandardBias equals DaylightBias).

TIME_ZONE_ID_DAYLIGHT

The operating system is operating in the range covered by the DaylightDate member of the TIME_ZONE_INFORMATION structure.

If the function fails, the return value is 0xFFFFFFFF. To get extended error information, call GetLastError.

Remarks

All translations between UTC time and local time are based on the following formula:

 

UTC = local time + bias 

 

The bias is the difference, in minutes, between UTC time and local time.
