Hi Guys,
A weird problem. I have disabled ntpd daemon on a HP server and placed
ntpdate in crontab instead and redirected the log to a file. This command
in cron synchronizes the server with a local time server every 15 minutes.
The weird part is that on 3 specific times (5:00 am, 10:00 am, 15:00 am)
the offset is BIG. 15 seconds for example. Take a look at this log:

I am really confused. Why
this happens every 5 hours exactly on those times?? Any idea?
I appreciate your help.

Just a thought.
Is there maybe something else in your crontab file that runs at 5:00, 10:00 etc that conflicts with this process?

maybe your server is just doing what the time server is telling it to do...
