Synchronize your NTP time using pool.ntp.org: the internet cluster of ntp servers
Posted by jpluimers on 2011/07/15
If you use NTP for syncing your time, then choose pool.ntp.org as your time server:
The pool.ntp.org project is a big virtual cluster of timeservers providing reliable easy to use NTP service for millions of clients.
I use it for instance to synchronize the time on my ESXi servers.
Note: when you run Windows VMs as ESXi guests; let ESXi time-sync them through the VMware tools, and disable Windows’ own time syncing. I didn’t disable it, and my Windows VMs were consistently off by over 30 minutes.

VMware’s best practice is to disable time sync with the ESXi host for VM timekeeping – http://kb.vmware.com/kb/1318

It is good not to only rely on pool.ntp.org. Some people argue that not all servers in that pool are sufficiently reliable.

Please elaborate. ‘some people’ and ‘not all servers’ is a bit vague ;-)
