Time not correct when returning from Q4OS to Windows

q4osfan · 2018-02-25 15:41

Have Q4OS on a USB stick and it works wonderfully.
Have set the time and date etc. via the Control Panel in Q4OS to Denmark, and it looks alright.
However, when I shut down, and open Windows(7) the time has moved to 1 hour earlier (though it says in the window where you can change the time in Windows that it the right time zone). I can then easily change the time 1 hour again - but why does this happen, and how to prevent it?
Thanks for any answer!

Hello and welcome!

As I recall Windows 7 gets its time from the BIOS - I have had the same issue on the rare occasions I swapped out the HD from a machine so I could run a Windows prog - Time Zone went wonky. I think it is down to UTC versus Local Time but haven't anything concrete to add.

Best solution - just use Q4OS

Hello, and welcome,,
bin is correct, happened to me going from 8.1 win to q4os . One is local the other UTC,

How I solved this was looked up local or UTC time in Ubuntu forums , sorry lost the bookmark, and found how to correct it two different ways,

Its something like ,. load correct local time in Linux app clock, then shutdown, log into windows put in line to use the linux time not the windows time .

then , shutdown , go back into linux , reload the local time , then shutdown again, and next time you switch they stay in sync.. maybe try how

to sync win.local with linux time ,,

sorry I cant help more than that, I really thought I saved the bookmark, I will also have to look it up again in future as I exactly cant remember .

I do remember it was go back an forth a few times , and there was two ways to do it , on the Ubuntu forums. I wasnt too hard after

you decide which way of the two, you want to do it , the choices are both local or both UTC, the second is more involved , I choose local, been fine sense,

problem is, If I have to do it again I need to find the forum post again. At least It steers you in right direction, good luck,

If I find post Ill let you know

found notes: you must edit file, /ect/adjtime/ UTC.....change UTC to LOCAL either just exit or save ,exit,

shutdown linux, relog in to linux, then shutdown again ...then log into windows then shutdown, relog into linux and now they should be in sync

Alternatively you may eliminate "automatic time synchronization" on your system:

$ sudo apt-get remove ntpdate

I've done that successfully:

Thanks to all!

Tried the last solution first - after entering the command sudo etc. I just got the message:

package 'ntpdate' is not installed, so not removed

Then I tried the other solution - changing UTC to LOCAL - and it worked! - after changing the time in Windows one last time again.

PS. I also discovered that /ect is named /etc in Q4OS!

- actually I thought /ect was normal in Linux and somebody inventive changed it to /etc in Q4OS - but now found that /etc is the standard everywhere (in Linux)
