Hi Dick,
These names carry over from well entrentched names from C. My guess is
format time and print time are what they are supposed to suggest.

I expect your speaking from a place of frustration. I don't think this is
the high point of the docs, but it isn't so bad as that. The strftime
method of a datetime object uses a mechanism similar to string formatting
to create strings displaying data from the datetime object. The docs for
datetime don't provide the details, pointing instead to the docs for the
very similar method of the time module.
I'm on my phone so cannot easily show an example but if d is a
datetime.datetime instance, d.strftime('%Y') will produce a string of d's
year.
Consult the time docs and see if you can get somewhere. If not, post again.
Best,
Brian vdB
