I have a problem with time when booting windows after linux. The reason is that Ubuntu saves hw clock as UTC but Windows 7 expects it to be saved as localtime. So Windows shows time that is one hour before correct local time.
- UTC time: 3:35PM
- Local time (UTC+1): 4:35PM
- Ubuntu time: 4:35PM
- Windows time: 3:35PM (it shows time that equals to UTC because it expects hw clock to be localtime)
I followed this advice:
To make MS Windows calculate the time from the hardware clock as UTC. Via regedit: Run regedit and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation Right-click in the right-side panel and select New > DWORD Value. Create the key named RealTimeIsUniversal and give it a value of 1.
After restarting, windows shows time that is 1 hour ahead. My timezone is UTC+1 but time is set to UTC+2. If I set timezone to UTC, time is correct.
- UTC time: 3:35PM
- Local time (UTC+1): 4:35PM
- Ubuntu time: 4:35PM
- Windows time: 5:35PM (it shows time that equals to UTC+2 but timezone is set to UTC+1)
Setting ubuntu to save hw clock as localtime solves the problem with time but I want to have hw clock set to UTC.
Any suggestions?
Thx in advance and sorry for my bad english :)
