Hi,

I've set up Ubuntu alongside Windows 10 and now have a trouble with the clock settings.

I want to the clocks show different in my different Operating Systems. For example, when I open Ubuntu it shows me 10:00 am (as I selected the region for clock in Ubuntu), and also it sets up this clock setting for BIOS and my other OS.

I want to stop this and be able to use for my Win. 10 OS different clock region, when I open Win. 10 and choose different region for clock as you predict this time the BIOS is set up this clock region and for Ubuntu's clock.

What can I do for this? Is there a way to do?

- Thanks.

Microsoft REQUIRES that the clock on the MOBO is set to YOUR LOCAL time -- best for a NON networked stand alone box
This was the way win1,2,3,3.1,and 95 were -- non networked standalone boxes

linux can also use the Microsoft time setting OR set the clock on the mobo to UT ( GMT) then adjust what is displaied on the desktop -- this is the BEST for a online connected world


with a dual boot
you HAVE TO !!!! use the Microsoft way ( no if's and's or butt's )


linux defaults to UT
there will be a setting to use local( Microsoft way)

The BIOS clock is either set to local or UTC/GMT time. Windows defaults to local and linux to UTC. This causes problems since upon shutdown linux updates the BIOS clock so that when you reboot to windows time will not be correct and vice versa.

You can change either Windows or Linux configuration to whatever BIOS clocking settings desired. With Ubuntu you can change the setting via the time/date applet. There should be a UTC checkbox in the time zone configuration window. Checked for BIOS clock set to UTC. Unchecked for local.

With windows (8 and 10) it is a registry setting. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation. Create new DWORD (32-bit) Value, name it RealTimeIsUniversal and set its value to 1. (I think this is correct)

I am lazy and keep the clock at local for dual boot. Since I don't dual boot anymore that isn't a problem...

Ahhh - and me with no Win8 or dual boot Win10 machines. Wondered why this was becoming an issue again.
About to dive into some Win10 (dual-boot) updates - thanks for bringing this up.
