Syncing Clock

[ggrot]

My servers' clocks get out of whack fast. By maybe 5 minutes a week depending on the machine. Is there any easy way to sync the computer clock on a unix machine with some standard online clock somewhere?

I think nasa offers free time service.
I got the same situation. All boxes are out of synch by a lot.
Always was too lazy to configure it.

Might look into the Network Time Protocol. See the link below:

A simple

ntpdate -s -t 20 -u ntp1.t-online.de ptbtime1.ptb.de ptbtime2.ptb.de

as a cron job run hourly will keep everthing n´sync.

call net time \\server /set /yes

will syncronize your windows boxes with a Linux [kernel.org] box.

From the bottom of the xntp file:

NTP has been around for a long time, aims at keeping your clock within a few tens of milliseconds of true time. Probably overkill for a single box, so SNTP (Simple Network Time Protocol) was developed.

Lots of references in Google Directory [directory.google.com...]

I am currently still using a Win2K setup so I am not clear as to what is available on real computers, there are multiple SNTP clients for Win and there must be many for linux.

<added>NTP is (as I should have guessed) part of the redhat distribution, see [redhat.com...] </added>

Thanks Mohamed_E

I have been to lazy to figure out how to sync my clock. My Daughter keeps telling me to remember that no one else is on RedHat time :)

Andreas,
I knew there had to be something fairly easy like that. I was getting ready to write a script to parse an HTML file I found online with a time from an atomic clock. This is far easier. Thanks.
