The FileTimeToLocalFileTime function converts a file time based on the Coordinated Universal Time (UTC) to a local file time.

BOOL FileTimeToLocalFileTime(
  CONST FILETIME *lpFileTime,  // pointer to UTC file time to convert
  LPFILETIME lpLocalFileTime   // pointer to converted file time


Pointer to a FILETIME structure containing the UTC-based file time to be converted into a local file time.
Pointer to a FILETIME structure to receive the converted local file time. This parameter cannot be the same as the lpFileTime parameter.

Return Values

If the function succeeds, the return value is nonzero.

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


FileTimeToLocalFileTime uses the current settings for the time zone and daylight saving time. Therefore, if it is daylight saving time, this function will take daylight saving time into account, even if the time you are converting is in standard time.
