The FileTimeToDosDateTime function converts a 64-bit file time to MS-DOS date and time values.
BOOL FileTimeToDosDateTime(
CONST FILETIME *lpFileTime,
// pointer to 64-bit file time
LPWORD lpFatDate, // pointer to variable for MS-DOS date
LPWORD lpFatTime // pointer to variable for MS-DOS time
);

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) |

0–4 | Second divided by 2 |

11–15 | Hour (0–23 on a 24-hour clock) |
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.
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.
