# LED Clock: You are (voluntarily) in a room that is completely dark except for
# the light coming from an old LED digital alarm clock. This is one of those
# clocks with 4 seven segment displays using an HH:MM time format. The clock is
# configured to display time in a 24 hour format and the leading digit will be
# blank if not used. What is the period of time between when the room is at its
# darkest to when it is at its lightest?
