Somewhat.
Years ago, the answer was to run NTP on the host and use VMWare Tools to help ensure that good quality time was served to the clients. That's when the earlier versions of the page at <http://support.ntp.org/bin/view/Support/KnownOsIssues#Sectio... were written.
Since then, that advice has apparently been recanted.
The ultimate problem with any virtualization system is the frequency and accuracy of clock updates to the client, and the loss of clock interrupts.
To the degree you can solve that problem, protocols like NTP can work reasonably well to monitor and correct for various types of known clock issues.
