date/time config in windows dual boot situation
 
Hi,

since I have this Windows 10 dual boot setup my Slackware time is 2 hours in the future.

And I have forgotten how to fix this, can anybody please tell me what do I need to do?

Thanks!

Windows date needs to be set to UTC I believe.

The other way is to modify /etc/adjtime to have the word LOCAL in it versus UTC.

Or so looking at /etc/rc.d/rc.S tells me.

Ah, this one has always been a pickle.

You see, Windows likes its time to be LOCALTIME and the bloody thing sets the hardware clock to LOCALTIME everytime.

So, generally when dual booting it is better to have the hardware clock to LOCALTIME. Set your hardware clock to the proper time, then run timeconfig to setup how Slackware will use the clock.

You might have to restart the machine and reset the clock to LOCALTIME before everything is fine.

Richard Cranium's post looks promising.

Just being curious ... what is your TimeZone and what is the offset from UTC ?

Thanks.

There's a windows registry entry you can change to tell windows that your PC is set to UTC. That's what I use and I've never had any trouble, even when the clocks change.

regedit, omg, is there no GUI option to make this?

Not that I'm aware of.

No, that's setting windows to UTC timezone. The regedit is for telling Windows that the BIOS time is in UTC but it can still use your local timezone.

Either configure the Slackware system to use local time or configure the Windows system to use UTC. To do the latter save the following as a *.reg file and run in Windows or manually edit the registry:

Code:
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation]
    "RealTimeIsUniversal"=dword:00000001

thanks a lot!, I am not surprised that Slackware itself provides the most easy solution
