All iMacs are displaying the wrong time... Also 1 iMac won't receive settings?

[abillybob]

Hi Guys

 

So I had all the iMacs pointing to our DC to get the time from although it seems since the time went forward for summer they are still an hour behind.

 

I have tried manually going into the settings and changing it to our mac server but that doesn't work and I've tried changing it to Apple's time server and it just won't change. Our Mac server has the correct time and so does all our other server including out DC so I don't understand really what's going on.

 

I have checked the time settings say British - Summer time on the iMacs and can ping all our servers and apple's server! Any ideas?

 

Also there is one rogue iMac that for some reason isn't getting settings from Workgroup Manager, all the other iMacs are working fine. The iMac in question can ping our Mac Server and will login users but just won't give them any settings...? On the mac server side of things all looks hunky dory...

 

Thanks peeps

Tried resetting any of them via terminal? sudo ntpdate -u time.apple.com if I recall correctly...

Yeah done that! Time shows 15:20 right now and when I do that command all it does is say the time was off by a couple of milliseconds...

Bump hoping someone will be able to help??

You tried changing your timezones over? I know there was (this was a while back though) an issue that "UK" didn't change but "london" did etc

Yeah I've tried doing that and changed them over to different UK cities although it didn't work so I've just changed them all back to their default of London. One machine seems to have got the latest time but all the other ar playing up... they're all setup the same do I don't know what else to do!?

After you have made a change (in System Preferences or via terminal or whatever) is that change reflected in /etc/ntp.conf?

 

We had this same problem since coming back, even though they already had the correct ntp server specified in system preferences I sent out the following via remote desktop...

 

systemsetup -setnetworktimeserver ntpserverip

 

...to force a rewrite of /etc/ntp.conf

 

After a restart the correct time was displayed again and users could log back in.

 

If the above doesn't work try removing ntp.conf, restarting, then changing the ntp settings.

Thank you just tried although this didn't work either Yes it's being reflected in /etc/ntp.conf
