Another short one , each time i open my bootcamp or VM (parallels or fusions) i get different timezone for windows and osx.
both are configured correctly connected to the internet and updated from ntp server.

But the windows machine is persistently offsets by two hours. After some hunting around and some trial and error I found that the best and quickest solution is adding a new registry key to HKLM\SYSTEM\CurrentControlSet\Control\TimeZoneInformation\ named RealTimeIsUniversal typed REG_DWORD and set it’svalue to 1


you can also patch your registry by downloading bootcamp clock registry update and running it on your windows machine.
