I have Macbook Air 13-inch, Mid 2013 and I am running Fusion Professional Version 6.0.2 (1398658). The VM is running Windows 7 Enterprise 32-bit. The Mac OSX version is 10.9.1 (Mavericks). VMware Tools are install and up to date.
When I start the VM the clock is correct. I usually leave the laptop running and when I step away and it goes to sleep, the clock on the VM is behind what appears to be the time it has been asleep.
I had this same set-up on MacBook Pro 17-in (I think this one was mid/late 2011) and I did not have this problem. That one too was left on and would sleep but the clock would sync back up when it came out of sleep.
I know the MacBook Air has the latest Intel processor (i7 in my case), so I didn't know if that might have something to do with how the clock works.
Anyone else seen this issue and if so, were you able to change a setting to get the clock to sync when you come out of sleep?
