google "current time gtm" 3 minutes different from ntpdate -q time1.google.com

[Walker Rowe]

I don't know if a firewall is causing me to fallback to the system time but for every time server I check the different betweem google "current time gtm"  and the time at time1.google,com is off my 3 mintes.  same with time-a-g.nist.gov.  using ubuntu 14.04

ntpdate -q time1.google.com
server 216.239.35.0, stratum 1, offset -172.653829, delay 0.14058
server 2001:4860:4806::, stratum 0, offset 0.000000, delay 0.00000
14 Feb 08:40:21 ntpdate[16631]: step time server 216.239.35.0 offset -172.653829 sec

Are you using ntpd to steer the local clock as well as running ntpdate?  The -q flag only queries the remote server and doesn't set the local system time.  ntpdate without the -q flag would attempt to do so.

Can you also show the output of "ntpq -c pe", if you are running ntpd?

If you are seeing a 3 minute offset to both Google and NIST, I suspect that your clock is not being steered at all, and your system clock is drifting; I'd expect to see that ntpd is not running, or it can't connect to any configured peers.

This is a VM and I opened ticket with cloud provider to have them look at the hypervisor level.  I think the have fixed the time now.  Here is output of that command.
