Date and Time not sticking?

TenneR · 25 Jan 2017

Bit of a strange one this, but I have an Asrock H97 Performance m/b and have changed the battery to see if that was causing the issue.

When I change to current date and time in the BIOS, it seems to run fine and reports correctly under Windows. However, when I come back the next morning (having been off overnight), the date/time reverts back to sometime in November 2016.

I think this is the time when I imaged my drive and is what's currently running (that is the deployed image).

When I change the date/time within Windows and reboot, the BIOS would correspond with that change done within Windows?

Any ideas?

Are you sure you put in a good battery and that it is installed correctly (not flipped over - upside down)?

Yep - pretty sure it's a good battery. Probably need to try another.

I've a feeling it could something to do with the image?

The CMOS and Bios are not a part of the Windows OS, they have their own little OS that runs the hardware. If the time is not staying in the Bios, then the battery is bad or the motherboard connector to the battery is not working.
Try Updating the Bios then switch out the battery: http://www.asrock.com/mb/Intel/Fatal1ty%20H97%20Performance/?cat=Download&os=BIOS

Or your windows is set to the wrong time server and changes it on start but that should have the year right. When you set the time inthe bios you do choose save not just back out without saving. Set it in bios save it power off go straight to bios is it correct if so its windows if not its battery or mb

I've never had the date/time an image was created or restored affect the system time.

Sounds like a CMOS battery issue. A new battery can be a dud, its rare but can happen. Also check the manual for the BIOS reset jumper and make sure its in the correct position. Best guess is Nov 2016 may be the date that BIOS was released, and thus the date it defaults to if it loses its settings. If it is the CMOS battery, I would expect other settings to be defaulting too, like boot order etc.

Having monitored this over the past week or so, if I connect my win 10 ssd, it would usually boot up fine and show correct and date (but see below).

If I switch over to my HDD (where I've deployed an image that was done back in November), and set the correct time etc., it would almost be guaranteed that the date/time would revert back to November 2016 if I leave it off overnight.

Strange thing is, it would also change the BIOS time after it's booted into Windows.

If plug the SSD back in, it would sometimes show the correct date (but the BIOS would remain in Nov 16) OR it would sometimes show the last time the SSD was shutdown?
