How do you handle sleeping host computer and keeping time in sync?

Each day I sleep my computer and wake it up on the next work day.  I do this so my desktop and applications are right where I left off vs shutting down and booting up then starting all apps again.

When I wake my computer, the Ubuntu virtual machines all keep the time as when I slept.  So if I sleep my Win7 computer at 5pm and then wake the next day at 7am, my Ubuntu VMs all show clocks of 5PM yesterday

I've tried using the vmtools time sync and in my .vmx file I have the following

tools.syncTime = "TRUE"
tools.syncTime.period = 60
time.synchronize.continue = "TRUE"
time.synchronize.restore = "TRUE"
time.synchronize.resume.disk = "TRUE"
time.synchronize.tools.startup = "TRUE"

However that doesnt seem to update any of the clocks. 

I realize most VMWare articles say to use ntp, but it seems like I have to run ntpdate every morning or stick it in a 5min cron job so I dont forget
