# A script that receives start and end parameters in the format HH:mm and
# exit with an error code if the current time is not within the desired
# window.
# The given times are not inclusive, so if you want 06:00-10:00 inclusive
# you need to specify 05:59 and 10:01 respectively.
# This script assumes that we are interested in time periods shorter than
# a single day, and it handles overnight periods.
