I have a few dedicated servers and for some reason they are totally unable to mantain the time properly synchronized, every few days they start having differences of minutes in the clock. So I have to manually open Putty, connect, login, and run the
ntpdate -u 0.ar.pool.ntp.org command on each of them.
Since there's no way I can do this every day because I'm quite busy, the question is exactly how can I create some kind of cron that auto-runs this command every day on each server. I have full root access to all servers, they have CentOs and DirectAdmin. Thanks.-
