The conversion code was moved to FILE_TIME_to_time_t_nsec() in
Python/fileutils.c.
time_t is a signed 64-bit integer type, so there's no immediate problem storing
1601-01-01 as the negative (pre-epoch) Unix timestamp -11644473600. But there
are indirect problems with using negative Unix timestamps in Windows. In
particular, datetime.fromtimestamp doesn't support them:
>>> datetime.fromtimestamp(-11644473600)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [Errno 22] Invalid argument
