The clock keeps effing up when I boot to Windows. Whats up?

[ConnerGDavis]

Every time I boot into Windows, the clock goes ahead by 7 hours. This wouldn't be AS annoying if it didn't subsequently break Skype -- because Skype thinks all the messages that I receive are based around that time. So whenever I type into a Skype chat and the person/people I'm talking to said something between the last time I logged in, all my messages will start to appear in the middle because the time has finally been corrected. It's hard to explain but very obnoxious and I've had to continuously flush all my Skype messages to prevent it from happening.

I suspect the reason is because I just installed #! CrunchBang Linux onto my 2nd hard drive, but I don't know how that would affect Windows' time. All I know is that it started happening after I did that. For more clarification: I have Windows on my first hard drive with an untouched MBR, then Linux on the 2nd hard drive with its own GRUB bootloader (if I want to start Linux I just change the hard drive it tries to boot to, this prevents me from having to deal with fixing MBR later on should I choose to uninstall Linux). I also have an NTFS partition that's about 200 GB on the second hard drive so I can still store some data for Windows (specifically, backup stuff) since that drive is huge and I sparsely use Linux.

Anyone have any ideas? This hasn't happened for my previous installations of Linux and I have used #! before so it isn't the distro specifically. I will be crossposting this to their forums as well. Thanks!

Edit: also, no I have not changed timezones, I've always been connected to the internet as usual, etc

Maybe a new battery.

Maybe a new battery.

What makes you say that? (totally curious) I've had this laptop for 2 years, I don't really know how long they're supposed to last.

 

[Dude]

Usually several years, but they are cheap and worth a shot

The CMOS battery will last anything up to 5 years - windows takes its data from the BIOS clock, in the first instance, which is then fine tuned by the internet call - but this may be set to only check every week or few days.

One way to check the clock battery is to set the clock in the bios, unplug the mains lead, & shut down the laptop and remove the main battery overnight - if the battery is good the time should be still correct the next morning.

If the battery is depleted, it will depend on the model of the laptop as to has simple the replacement will be, some can mean a complete disassembly to get at it

Battery is really easy to get to, it's the corner of the back of the laptop and you just pop it right out (Asus G74sx). I've got the $ so I'll probably just grab a replacement as soon as I can. Thanks

Usually the Cmos battery failing will revert the mobo time to manufacture date of the bios not Ahead 7 hours. This sounds like there is an issue with some program modifying time settings when windows loads. Like a third party program of some sort. either that or something within the boot up is looking in the wrong time zone even though windows has it set correctly.

I would look in startup and msconfig to see what is running at bootup

 

[Layback Bear]

Me neither mohavepc, never seen one go forward unless the time zone was not correct or a 3rd party program doing crazy things. That being said. The bios battery is cheep and ConnerGDavis said it was easy to replace so give it a go.
I have brand new bios batteries that were no go.
A while back I read about a infection that changed the time so one couldn't get updates to Windows or security programs.
Can you still get updates and have you run any security scans?

Doing this Tutorial by Brink would be helpful

Just downloaded an MSE definitions update to test that theory out and it worked just fine. Also checked my startup and everything there is what I want to be there. I run Malwarebytes scans weekly as well as MSE. The only actively running software I have is Steam, Skype, Amazon Cloud Drive, Google Drive, Google Music Manager, SpyBot (recommended by Google so I have faith that's a reliable program) and of course MSE. I keep this computer clean as hell so I have a really tough time believing anything is messing with it. Worst "infection" I've had is some spyware and that's why I bothered getting Spybot.

I understand Conner and it seems like your diligent but there are usually things running in the background most users don't see and never knew they were there. I know a lot of people don't recommend using msconfig as it is just a band aid but it will show you what is hiding as it were and then you can do a better cleanup job. I am not saying your infected or that is the only cause of this issue. What I am saying is it shouldn't be dismissed or overlooked. If you need help running msconfig just ask

Does the problem only occur after you have run your Linux install?
If so, try checking the time zone settings in the Linux install.

I have noticed, if I use a Live Linux CD/DVD the system time gets confused.
It doesn't happen with my Linux Mint install though.

I usually manually trigger the "Internet Time Settings" to fix the problem.

Someone might know how to force the "Internet Time Settings" to run at Startup.

[ConnerGDavis]

OK i just logged into Linux and the time was off by a few hours in that too... wat do? Clearly a connection now though.

Check the CrunchBang forums.
See if you can find a thread about using "Local Time".

In the Windows Task Scheduler there is a "Time Synchronization" task.

Task Scheduler > Task Scheduler Library > Microsoft > Windows > Time Synchronization
​

You could:

• "Export" that task (as a backup)
• Edit the "Trigger" (change from "Weekly to "At startup" or "At log on")

Create a System Restore point, or better yet, a backup HDD/SSD image before changing the settings.

That's a solid idea, thanks.
