My most recent stab at using ntpd with minpoll 4 polling of a local ntp time source isn't working, the clock drift prevents any sync from happening (but I'll admit not trying some of the more aggressive time adjustment options to ntpd). VMWare's documentation and support leans pretty heavily toward Linux and I'm not finding a decent recommendation from them. I rebuilding a kernel with options HZ=100 to see if that makes a difference, not sure why I remember that helping, but any other strategies known to work?
