Avoid 2:00 and 3:00 am cron jobs (2013)
! A word to the wise: Do not set any cron jobs for 2:00 am or 3:00 am on Sunday morning! Or to be safe, on other mornings besides Sunday as well, since jobs originally set to run on some particular day may eventually be changed to run on another day, or every day. Most of the time such cron jobs will run fine, but if they run every Sunday morning, then twice per year they will run at the exact time daylight savings time (aka summer time) kicks in or ends, sometimes with very strange results.
