FileTimeToDosDateTime function

Converts a file time to MS-DOS date and time values.

Syntax

BOOL FileTimeToDosDateTime(
  const FILETIME *lpFileTime,
  LPWORD         lpFatDate,
  LPWORD         lpFatTime
);

Parameters

lpFileTime

A pointer to a FILETIME structure containing the file time to convert to MS-DOS date and time format.

Bits Description
0–4 Day of the month (1–31)
5–8 Month (1 = January, 2 = February, etc.)
9-15 Year offset from 1980 (add 1980 to get actual year)

lpFatTime

Bits Description

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

Remarks

The MS-DOS date format can represent only dates between 1/1/1980 and 12/31/2107; this conversion fails if the input file time is outside this range.
