I run Ubuntu on one SSD, and then run Windows 10 pro on a seperate SSD. My default OS is Ubuntu (boot priority), and when I want to run Windows 10 pro I go into BIOS and select the proper SSD. This works just fine, and everything is fine.. but.. a minor "bug" is that when I load up Windows 10 Pro, the time is 6 hours off. I don't have this issue on Ubuntu. Time and Time Zone in Settings are set to automatic. The date is always accurate, but time is always off. Any suggestions? It's an annoying inconvenience.
