guess what,… its oct 23rd 2014 and this is still an issue. If I put my mac to sleep, my Parallels time pauses only to resume when my mac wakes up. So instead of being 8:56AM today, my windows is telling me it's 5:06PM the night before
It is now May 11 2015 and I am running Build 9.0.24251 on OSX-10 with Windows 7 - 64 as the VM and the time sync is still and issue. I tried the registry hack and it did not work. I can't believe how tone deaf Parallels is in this matter.
