[Discuss] Cron fail lesson of the day

[richard.pieri at gmail.com (Rich Pieri)]

Not a cron fail as such but at one of my early gigs I had a machine
with an hourly cron job that sometimes would run twice and sometimes
not run at all.

Turned out there were two time sync daemons running using different
time servers and those two servers were far enough part that the system
time intermittantly skipped past and back over the hour mark.
