Computer Time Is Wrong After Being Shutdown

[TheStyne]

Whenever I shut down my computer for an extended period of time(like an hour or so), the time is completely off when I come back. Sometimes it's ahead, sometimes it's behind, and not just by a bit, it's often not even the right date. 

 

I've been stuck just re-syncing the time every time I turn my computer on, but I would really prefer not to. I though it might be a CMOS battery problem, but all my BIOS settings remain intact, like my memory overclock. 

 

Does anyone have any ideas about what the problem might be? Could it maybe be some program? 

Thanks, Alex.

I'd first start by replacing the CMOS battery anyway. They're super cheap so no harm in doing so. Your board may store some UEFI settings in onboard storage, so even a dead CMOS battery might not reset them.

Is this related to the time on the system's motherboard or the time on your operating system (if it's on your OS then make sure that the time zone settings are automatically synced to your time zone and please include what motherboard + OS you are using)?

It's both of them, motherboard and OS. When I change it in the OS though, it automatically changes the motherboard time. I'm using Windows 10, and an MSI B350 Tomahawk. It's only two years old, so I'd be surprised if the CMOS battery is dead. I'm currently looking for another battery to try.

Then I would recommend changing the CMOS battery, make sure to backup/save any custom UEFI BIOS settings since your settings may clear after removing the existing battery. Depending on how long the system was left disconnected from power and quality of the installed battery, 2 years isn't that much of an extremely short time for a CMOS battery to finish or develop a short or some internal issue that prevents it from functioning properly.

I only had this a couple of times on older versions of windows years ago and sometimes I didn't even notice it for a couple of days.  

I saw it but it didn't register completely with me if you know what I mean.

I think I might have had it once also on windows 10 too.

 

It wasn't on the bios or at least I never looked so this might not be relevant.

I know this sounds obvious but all I did was go into Windows Security and run a full system scan.

That fixed it.

Then I ran windows update after.

 

You can also run a full scan with Microsoft's malicious software removal tool (type mrt in search and hit return).

Sometimes when windows 10 is acting janky and not running well for no apparent reason.

Just doing the mrt scan seems to fix it.

I have no clue why.  

 

Anyway I hope that is helpful to you.
