Thanks Tom and Dave for your answers. I double checked with real hardware - there it works - so this looks to me like a bug in ESXi5 running RHEL6/C6 and ntpd. We are running latest VMware ESXi5 patch 768111 and latest RHEL/CentOS. I followed VMware's best practices closely: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1006427 Means, no time sync using vmware-tools, just ntpd with no local timesource.
