Solved Clock in win8 changes time when I switch between OS's

[Erndog]

I have a dual boot set-up with 2hhd's. Win8 on one and Zorin9 on the other.
Whenever I switch from Zorin to Win8 the clock in Win8 advances by 5 hours
The time zone stays the same but the time changes
The clock in Zorin = no problem.

UTC? Try here.. Force Windows 8 to use UTC when dealing with BIOS clock - Super User

How old is your CMOS battery ?

Sorry, I can't spell your state. Boston is easier to spell for me. Check it out though - Boston is 5h off of UTC (or GMT if you prefer). That is almost certainly your issue rather than a co-incidence.

Lol on "can't spell your state", many folks in the US have a hard time with it.

See this from stack exchange. I had the same problem with Windows 7/Ubuntu 13.10 dual-boot. That I decided to stay dual boot I just Saved this on an external disk to remember for all Ubuntu(on which Zorin is based) distros: [h=3]Make Linux use 'Local' time[/h]
To tell your Ubuntu system that the hardware clock is set to 'local' time:

1. Open a terminal and type:

    edit /etc/default/rcS

2. Then add or change the following section: #

    Set UTC=yes if your hardware clock is set to UTC (GMT)UTC=no

[h=3][/h]

Thx, but when I typed edit /etc/default/rcS I got warning: unknown mime type
????

In the case of Ubuntu it's

[FONT=Courier New]gksu gedit /etc/default/rcS

[DEL]I'm not sure if it's the same with Zorin.[/FONT][/DEL] Oh I just searched on Zorin site, yup it is if you're using Gnome text editor. I left it open the first time because different distribution use different text editors.

The time zone stays the same but the time changes

I regularly run into the very same problem after I install a new Linux distro -- as Linux default to UTC, while Windows defaults to local time.

The fix I use is described in post #8. You need to use gksu because you must edit that file as ROOT -- not your usual user id.

That is the same issue I had with Xubuntu. That fix worked like a charm to stop the 5 hour difference. Linux likes to go in and advance the bios clock for some reason. I do not know if they fixed it with the newest kernel.

If the OP has not enabled Root, they will have to do the following "sudo passwd root" in a terminal window.

Nano is a good one, Gedit is what I use all of the time.

It seems like I'm caught in a loop which goes like this...
-I reset the time in Win to 10am
-I checked the BIOS and it said 10am
As long as I stay in Win the time remains correct
-Open Zorin and the time said 5am BUT! after about 30 sec. it corrected itself to 10am
-I went back to Win and time was now reset to 3pm
-I check the BIOS and it was also reset to 3pm

Here is a sreen shot of the T window, not sure whats going on?

I really appreciate all your help

Looks good. read this thread at Ubuntu forums. They have a lot of dual booters.

[h=3]You will have to use Sudo to make the changes.

Make Linux use 'Local' time[/h]To tell your Ubuntu system that the hardware clock is set to 'local' time:

1. 
   [*=left]edit /etc/default/rcS
   [*=left]add or change the following section# Set UTC=yes if your hardware clock is set to UTC (GMT)
   UTC=no

 

[Erndog]

It worked. The timed arwe correct for each OS.
Thank you everyone for all your help!

Glad to help, I had the same problem on my Ubuntu/Windows 7 dual boot laptop.
