I've not used the ESXi hypervisor, but do use ESX 3.5 with FreeBSD, and the
only way I've sucessfully kept FreeBSD servers in time, is to use either
ntpdate or ntpd. Lately, I've found ntpd to be a better solution. Vmware
have a KB article on the best way to configure ntpd on a virtual machine:
For what it's worth this is the ntp.conf I use, which gives me no trouble:
tinker panic 0
restrict default kod nomodify notrap
