How to update the hosts clock as part of cron daily?

[Ernie Luzar]

Hello List;

My host motherboard clock is losing about 3 seconds a day.
I have replaced the the motherboard battery but this did not help.
So now I want to run "ntpd -q" or ntpdate once a day as part of 
cron:periodic:daily.
I see 480.status-ntpd but no info on what it does or how to active if.

What is the normal practice to accomplish this?

Thanks
Ernie
