[Tutor] deleting files that are older than x days old

[Mike Hansen]

 From a python program, I want to delete certain files that are older than x 
days old.

To get the time that the file was last modified, it looks like I need to use 
os.path.getmtime(path). This gives you the time represented in the number of 
seconds from the epoch.

I'd like to convert this into a datetime object, but I can't seem to figure out 
how. Once it's a datetime object, I can do simple (datetime.datetime.today() - 
filedatetime).days to figure out the days old.

How do you convert a time represented in seconds from the epoch into a datetime 
object?
