NTFS file timestamps, according to the documentation of the ‘FILETIME’ data structure in the Windows Software Development Toolkit, is a “64-bit value representing the number of 100-nanosecond intervals since January 1, 1601 (UTC)”.
Conversion from this internal format to a format more suitable for human interpretation is performed by the Windows system call FileTimeToSystemTime(), which extracts the year, month, day, hour, minutes, seconds and milliseconds from the timestamp data. On other platforms (e.g. Unix), or in software that is intentionally platform-independent (e.g. Perl or Java) other methods for translation is be required.
The documentation of FileTimeToSystemTime(), as well as practical tests, indicate that the FILETIME value to be translated must be 0x7FFFFFFFFFFFFFFF or less. This corresponds to the time 30828-09-14 02:48:05.4775807.
