I think this is partially due to a misunderstanding, both by Microsoft,
and in Python. There is a long-time myth that ctime denotes "creation
time", as this is really in-line with mtime and atime.

I think the path module should provide these under a different name:
creation_time and status_change_time. Either of these might be absent.
ctime should be provided to report whatever ctime used to report in
the past (i.e. creation_time on Windows, status_change_time on Unix).
