I have something similar in my crontab which is not exactly what I
need.  I want to make sure that the clock is set at every boot because
I'm using this as a kerberos server.  If the clock is not set properly
at boot, kerberos will not work properly until the nightly cron jobs
are run and the clock is set then.  I need everything working at boot.
 I can't have a window of problems between boot and midnight or
whenever cron runs ntpdate.
