BIOS date and time keeps resetting

The clock in your Windows computer can be configured to sync with an Internet time server, which can be useful as it ensures your clock stays accurate. In cases where your date or time keeps changing from what you've previously set it to, it is likely that your computer is syncing with a time server. For example, if you like having the clock on your business computer set a bit ahead, the time changing without your knowledge could make you late for a meeting. To prevent it from changing, disable time syncing.

1.
Right-click the time and date display on the right side of the Windows taskbar and select "Adjust Date/Time."
2.
Open the "Internet Time" tab in the "Date and Time" dialog box that opens up and then click the "Change Settings" button. Confirm the operation or type in your administrator password, if prompted.
3.
Click to deselect the check box for "Synchronize with an Internet Time Server" and click "OK."
4.
Click "Apply" and "OK" to save your settings. The date and/or time won't change on your computer again.

It might be helpful if you provide the hardware that your system is running on. A lot of systems use a small battery to save the system clock in the BIOS.

I should mention that if I change the time in the bios and reboot or shut down without letting TrueNAS boot up the clock is fine. After TrueNAS boots up that's when the time changes in the bios.

Have you tried changing the date/time and then powering the system off completely by unplugging the power cable? Then go back into the BIOS and see if the time and date is still correct. I suspect it’s hardware related. I would double check the battery on the motherboard. Is it off by an exact amount of time? Or just random? Perhaps the time zone isn’t being saved within TrueNAS.

Yes if I set the time in the bios it hold if I reboot back into the bios or unplug the power it still holds. It only changes if I let the PC load TrueNAS
From what I see it sends the bios 6 hours ahead. I live in MN so central. Im trying differnt time zones in TrueNAS to see what I get

What do you mean by "correct time in the BIOS"? TrueNAS like all Unix systems runs the local clock in UTC and converts the time for display to your local one. So this should not be a problem unless you are dual-booting the system with an OS that expects local time in the system clock like e.g. Windows. But you don't dual boot a NAS server, do you?

No, just a fresh install of Truenas. I use the turn on feature in the bios to start the system up everyday. I tried a lot of different time zones but the time in the bios and Truenas don’t sync up. Every time I use central time in Truenas the bios jumps six hours ahead.

But again I know it’s not the motherboard because I can set the time in there and as long as Truenas doesn’t load the time is correct. I even tried shutting the computer off for an hour and a time is still good. But after I let trueNas load then go back to the bios the time has been changed.

I’m sure no one really cares what their time shows in the bios. 98% of people using it let it run 24 seven I bet. But could someone maybe check to see if their bios is showing the correct time?

Well since Central Time is GMT -6, that explains that it’s a time zone issue. Perhaps try and change the time zone in TrueNAS to something else and then back again.

Everything correct here. You must run your BIOS clock in UTC and set your local timezone in TrueNAS. It won't work any other way.

The only option I seen in the bios was the hour, mins and date. I’ll look for it when I get home.

I might just set the wake up time 6 hours ahead so it turns on when I want it to. It worked this morning so it’s a work around.

Yes. And you set the hour and minute to the current time in UTC, not in your local time. The BIOS does not have a concept of time zones but Unix assumes that the "hardware clock" is running in UTC.

It's working so far. I set the bios turn on time to 1500 hours and that would be 9:00am
And the Cron job is working to turn the server off at 1:30am so im all good now.
Thanks everyone.

You can set the proper timezone for your system from the System/General tab. Under the localization options you can set both the Timezone and Time Format for display.

Why does my computer keep resetting the time and date?

In cases where your date or time keeps changing from what you've previously set it to, it is likely that your computer is syncing with a time server. For example, if you like having the clock on your business computer set a bit ahead, the time changing without your knowledge could make you late for a meeting.

Why is my BIOS clock wrong?

However, when CMOS battery goes bad or drained, the chip starts losing information. One of the signs indicating this is that your computer displays incorrect date and time. To solve this issue, you will need to replace your computer's CMOS battery.
