    Problem with Time Protocol in ESXi 5.1.0 1065491

    Michael_Jervis Lurker

      I am having issues with the time on my ESXi 5.1 (1065491) VMware farm. The farm consists of three separate physical servers (2 - Dell PowerEdge 1950, 1 - Dell PowerEdge 2950). The Virtual Center Server is a VM on the farm housed on ESXi2, it displays the correct time as well as the SQL Server which is also a VM housed on ESXi3. There are no VMs on ESXi1 currently.


      The time keeps jumping 4 days and 3 hours into the past no matter what I do. I am using NTP but still the time skews. I change it manually with the following commands:


      hwclock -d 01/05/2015 -t 14:06:00

      esxcli system time set -y 2015 -M 01 -d 05 -H 14 -m 06 -s 00

      esxcli hardware clock set -y 2015 -M 01 -d 05 -H 14 -m 06 -s 00


      It then shows the correct time in vSphere Client then between 30 secs to 1 min it reverts back to the past. Time when it reverts displays 01/01/2015 06:05 on all three servers. It shows that NTP Client is running and the correct NTP servers are listed.


      The /etc/ntp.conf looks like this:


      restrict default kod nomodify notrap nopeer


      server ##.##.##.##

      server ##.##.##.##

      driftfile /etc/ntp.drift


      Where ##.##.##.## is the internal IP addresses of our NTP servers. The /etc/ntp.drift looks like this:


      ~ # cat /etc/ntp.drift



      In Configuration => Software => Security Profile => Firewall Properties, SSH Server, SSH Client, and NTP Client are enabled.

      In Configuration => Software => Security Profile => Services Properties, NTP Daemon and SSH are running.


      I am at a loss...
