Time Delta

[Jonathan R. Lusky]

Don't let the ntpd weenies hear you suggest cron'ing ntpdate--they get
pissy about how bad that is :).

For the rest of us who don't give a damn about more than 0.1s accuracy
on their system clocks, and especially anyone who got rooted by the last
big ntpd vuln, ntpdate cronjob works fine.  One caveat though--you probably
need to do it more than just once a day.  I usually do every 30 minutes.
When you run ntpdate, you'll see that it says "adjust" or "step".  The only
time you should see "step" is the first time you run ntpdate after
booting, or if the NTP servers have been unreachable for an extended period
of time.  If you're seeing it regularly, it means your interval between updates
is too large.
