> as your "ntpdate -qu"The big problem with ntpdate and rdate is that they step the clock. That is only appropriate at boot time. Stepping the clock has the potential for all kinds of clock stepping issues. Mostly when cron has a task a exactly some time and that time never hits because the time stepped past it. Or the task runs twice because the time stepped back and hit it again. Why do you need to step the clock? It is better to install ntp and adjust the rate of the clock so that every tick is seen but adjusted to be in time with the rest of the world. Bob
