gh-98378: Add small format string example to strftime comments (GH-98379)

zvory · web-flow · commit 6ccca69d0d31 · 2022-10-18T06:42:10.000-07:00
A small example of what a full date and time would look like would help a lot of developers who may not realize that they should investigate `time.h`'s `strftime`, run `man strftime`, or click through a series of docs on the python docs before they get to the actual [definition here](https://docs.python.org/3/library/datetime.html#strftime-and-strptime-format-codes) which still doesn't have an obvious copy-pastable example of "what the heck format does this thing actually expect?".
