Ntpdate not updating time
The cost is a little processing power and memory, but for a modern server this is negligible.

Note that it can take several minutes before your NTP server is able to provide time services to downstream clients.First, check the stratum level of your server: ass ID=0 status=c011 sync_alarm, sync_unspec, 1 event, event_restart,version="ntpd [email protected] Tue Jul 6 UTC 2010 (1)",processor="x86_64", system="Linux/2.6.32-200.19.1.el6uek.x86_64",leap=11, stratum=16, precision=-20, rootdelay=0.000,rootdispersion=1.020, peer=0, refid=INIT,reftime=00000000.00000000 Thu, Feb 7 2036 .000, poll=6,clock=d21d4a96.a26c5962 Fri, Sep 16 2011 .634, state=0,offset=0.000, frequency=0.000, jitter=0.001, noise=0.001,stability=0.000, tai=0 , wait a few minutes and try again.$ sudo ntpdate org 31 Aug ntpdate: the NTP socket is in use, exiting $ sudo service ntp stop [ ok ] Stopping NTP server: ntpd.$ sudo ntpdate org 31 Aug ntpdate: adjust time server .115 offset -0.002893 sec $ sudo service ntp start For people reading the way above, though it technically works, look below at superuser.com/a/639516/308927 because it's way simpler (single command, no need to twiddle with stopping/starting the service).
I would check the 2 other boxes DC1 & 3 to ensure they are getting the correct time. 1 u 40 64 377 9.468 0.209 0.129 -PRIVATE3 126.96.36.199 2 u 12 64 377 6.943 -0.270 0.142 -PRIVATE5 .
This post will explain how to configure NTP on your Oracle VM Manager to provide time services.
Prior to starting this process, you should ensure that your Oracle VM Manager host is either registered with the Unbreakable Linux Network (ULN) or configured to use Oracle's public yum service.
You may want to check with your network administrator if time services are provided on your corporate network and replace these entries.
To change your upstream time servers, search /etc/for: And replace with entries that refer to your local time server names or IP addresses.
Behind this simple description, there is a lot of complexity - there are tiers of NTP servers, with the tier one NTP servers connected to atomic clocks, and tier two and three servers spreading the load of actually handling requests across the Internet.
