It's the number of seconds before the hardcoded leap second time (1 Jul
2015 00:00:00 UTC) where the time fed by the program should start. E.g.
if it was 600, it would start 10 minutes before the midnight of the leap
second. You would probably want to start with a larger number (if you
don't want to test a leap second) and also change the LEAP_TIME constant
to a current date.
