How check if current date and time is after a given date and time
Question: In Python:

  1. How check if current date and time is after a given date and time object named "next_check"
  2. Add X number of minutes to next check


Answer: You can do both of those things with
[`datetime`](https://docs.python.org/2/library/datetime.html) (assuming you
`import datetime` and `next_check` is actually a `datetime.datetime`
instance):

  1. `if datetime.datetime.now() > next_check`; and
  2. `next_check += datetime.timedelta(minutes=X)`.

If it isn't a `datetime.datetime` instance, that module contains various
functions (e.g.
[`strptime`](https://docs.python.org/2/library/datetime.html#datetime.datetime.strptime))
to make it into one.
