LocalFileTimeToFileTime function

Converts a local file time to a file time based on the Coordinated Universal Time (UTC).

Syntax


BOOL WINAPI LocalFileTimeToFileTime(
  _In_   const FILETIME *lpLocalFileTime,
  _Out_  LPFILETIME lpFileTime
);

Parameters

lpLocalFileTime [in]

A pointer to a FILETIME structure that specifies the local file time to be converted into a UTC-based file time.

lpFileTime [out]

A pointer to a FILETIME structure to receive the converted UTC-based file time. This parameter cannot be the same as the lpLocalFileTime parameter.

Return value

If the function succeeds, the return value is nonzero.

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

Remarks

LocalFileTimeToFileTime 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.
