[SOLVED] Windows and arch dualboot time problems

RounakDutta · 2022-03-05 17:22:35

I did a arch and windows dualboot but my windows was showing the wrong time so I decided to manually set the correct time for windows and then after 5 or 6 hours when I booted into my arch linux it started showing the wrong time. I decided to manually set the correct time for linux but now my windows is showing the wrong time. I want both of my operating system to show the correct time . GMT +5:30 (INDIA)

Configure Windows to use UTC: https://wiki.archlinux.org/title/System … ft_Windows

I added the registry key through command prompt and then I booted into linux and I did hwclock --systohc but still the problem persists.

Give us the output of `timedatectl` so we can first make sure everything is set right in Arch and the RTC

So that's where you need to start, your time in Arch is way off. You did hwclock --systohc, but did you set the system time first?

Oh ok now I got it I did -
timedatectl set-time "2022-03-05 23:14:20"
sudo hwclock --systohc

Now it is working.

You might want to consider enabling time synchronisation to prevent that from drifting away, with timedatectl set-ntp true for example.

In any case if this is solved, please mark it as such by editing the title and adding [SOLVED]

Ya I already did

ln -sf /usr/share/zoneinfo/Asia/Kolkata /etc/localtime

during installing arch but still whenever I finish installing arch the time synchronisation just turns off idk why.

That just configures which timezone you're in and doesn't account for potential clock skews which can happen over time: https://wiki.archlinux.org/title/System_time#Time_skew
