Re: [gentoo-user] Dual OS clock issues
Maybe this is doesn't help. But I had problem like that before when I created dual boot system (Manjaro and Gentoo). My hardware has local time. So I can fix it with Manjaro on local time and Gentoo on UTC time or vice-versa. Regards, Ramdziana On 06/05/2015 02:06 AM, Derek Ellison wrote: I have two HDD in a UEFI system.

See https://wiki.archlinux.org/index.php/Time#UTC_in_Windows -- Fernando Rodriguez Given the fact that the builtin network time sync windows does ignores that feature altogether, it's generally a lot more sensible to configure the OS that actually cooperates rather than the one that only listens to settings when it suits it. That said, when there's some reason that's not an option (in my case, I'm not the admin on the linux OS some of my machines are stuck dual booting with, and I need reliable time sync in windows for licensing), a secondary tool like NetTime, alongside disabling the W32Time and setting RealTimeIsUniversal in the registry seems to work well so far. -- Joshua M.

The main problem is that Windows will change the local time twice a year on DST zones, aside from NTP how can Linux tell if the time is adjusted? So if you boot while offline you may end up with the wrong time or you may have the time adjusted back and forth everytime you boot the other OS so any files touched during early boot end up with wrong times. Also on Windows that's the only setting, on Linux you also have you desktop environment settings to worry about so the simplest way to get it to work all year long is to set Windows to use UTC and disable time sync in Windows as shown in the link. Unless your system clock drifts badly the lack of time sync in Windows is not a problem for most users, the rest can use an NTP service on Windows too. -- Fernando Rodriguez

Timezone is Pacific US or America/Los_Angeles. I'll look into the hwclock and see what I can do.

If that clock is set to the local time, then # set CLOCK to local. Note that if you dual boot with Windows, then # you should set it to local. MSWindows overwrites the hardware clock with the local time on shutdown. You can either define your Gentoo hardware clock as local in /etc/conf.d/hwclock, so that it is the same with MSWindows ... or set it as UTC and fix MSWindows to treat the hardware clock as a UTC setting too. Add a new registry key in MSWindows: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation] “RealTimeIsUniversal”=dword:0001 -- Regards, Mick signature.asc Description: This is a digitally signed message part.
