I have the same errors on my x98 Air 3G C5J6. I also adjusted the time. but at the next boot so it is 2 hours wrong again. Hope someone has the solution.
1.run regedit.exe
2.locate this path HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation\
3. right click add DWORD ,rename it as “RealTimeIsUniversal” exactly
4.double click and Change the value of the RealTimeIsUniversal key to 1.
5.set your current time and time zone in the clock and restart the system.
6.switch os and check again.
Raj Lak, thank you very much! My X98 Plus II showed different times in Windows 10 and Android. Did your fix – now both operating system display the same time.
