This issue continues to persist. The option for synchronizing Time with OS X was already my default.
Please read this carefully:
- Start a Windows 10 VM under Parallels Desktop for Mac 11.
- Lock my OS X keyboard or let a screen saver kick in, blank the screen or whatever that would require my OS X password to unlock the system again.
- Leave the system for an hour.
- When I return to the OS X keyboard, enter my password to unlock the machine, the Windows 10 VMs clock is one hour behind! After a 3-5 minutes, Windows realizes this and synchronizes the clock again with OS X. The issue is that often it's more than the clock being behind, it's also killed my network connection and whatever tasks I left running on Windows 10 failed due to the lack of network connectivity.
Incredibly annoying behavior!
