Instead of formatting your other date to match the input, turn the
input into something you can easily manipulate - preferably, Unix time
(seconds since 1970, sometimes referred to as a "time_t"). Once both
your timestamps are integer (or float) seconds since a known epoch,
they can be compared directly, as numbers.

You're already pretty much there with strptime. Poke around with that
and play with your format string and you should have it. But you may
need to tweak it to match your actual input.
