- Clock time is off on dual boot 4 answers
I recently installed version Windows7 alongside my Ubuntu 14.04 and noticed that despite the time zone being in the correct setting (Pacific Standard time), that the Clock Was off by several hours in Ubuntu. I searched online for answers and read somewhere that deselecting the 'sync with internet clock' might help the issue. It did seem to resolve the issue for the short-term, but after some updates I have noticed once again that my system clock is 7 hours ahead. Looking into the BIOS I discovered that the clock there was being reset.
What brought it to my attention was that my f.Lux in UBuntu wasn't turning on at the right times, so I went and checked the time in BIOS and noticed that it was forward by 7 hours. This explains a few things, ans I suspected its probably the battery, BUT something weird is happening that tells me otherwise.
If I go into BIOS and set the clock to the correct time, and then load into Windows, everything stays fine. I can restart the system into Windows and nothing changes in the BIOS or Windows time. If I log into Ubuntu via the Windows bootloader the time changes in the Ubuntu Clock to be behind 7 hours. If I reboot again into Ubuntu the Ubuntu clock is still off and the BIOS clock is normal. The only time the clock chnage sin the bIOS is when I change the time in UBuntu clock, (either by selecting manaul or internet sync).
What is strange is that after the BIOS is modified to have the wrong time, the clock in Ubuntu will seem correct by displaying the right time. If I fix the time in the BIOS, log straight Into ubuntu wia windows bootloader, the Ubuntu clock will be off.
Its almost as though Ubuntu cant read the BIOS clock properly or sync with it.
