There were some also set to 2043 which is a valid datetime, albeit in the future, but they failed the same as the 1907 ones. Unfortunately Windows doesn't adhere to epoch time, I just edited the timestamps on a file - the minimum is 1st Jan 1601, so it needs to cope. Edit: January 1, 1601 NTFS, COBOL, Win32/Win64 1601 was the first year of the 400-year Gregorian calendarcycle at the time Windows NT was made.[12]
