I have a requirement to test the creation time of a file with the

Platform is Unix.
I have looked at using os.path.getctime for the file creation time and
time.time() for the current time, but is this the best approach?
Lots of people are confused by ctime because they think 'c' stands for
change. That's wrong. st_ctime is status change time. The ctime is
updated when you change (for example) owner or group of a file, create a
hard link etc. POSIX has no concept of creation time stamp.

I haven't thought this through too much, but perhaps an ugly
"work-around" would be to use inotify (in some kind of daemon) to watch
for the IN_CREATE events and store the crtime in a personal DB. Then
possibly look at some sort of scheduling to fulfil what happens after 15
minutes.
I'm sure there's subtleties I'm missing, but just thought it could be
useful.
