Here’s a clearer version of your message:

So, the details are: Why would the BIOS time differ in my W11 zone? I'm in UTC +2:00. If I adjust the BIOS clock to match my local time, Windows (11) shows 2 hours ahead. For example, setting BIOS to 21:00 makes W11 time 23:00. It seems this could be related to the system not waking from sleep or not turning on automatically by the set alarm. Is this just a coincidence or is there a real reason behind it? P.S. I wasn’t sure where to post this, so I’m sharing now.

In Linux systems, it's standard to maintain the BIOS clock in UTC. It seems Windows 11 might be moving toward aligning with this practice.

It seems like something unusual at the operating system level. Wasn't this expected before? My earlier tests showed consistency between BIOS and Windows clocks. Maybe my memory is off...

It should be the same.... Off topic question, Do you have Dram SPD write set to disabled or enabled?

You can't locate it in the BIOS settings, but it's likely in the system's advanced options or device manager.

Navigate to the lowest settings in the timing options menu.

Hmm, MSI and the terminology... Seems like a DIMM SPD alias. Could be related to the DRAM SPD write feature, though I’m not entirely sure. There was an issue with Taiphoon’s burner reading my memory after a batch of defaults last night.

And for the Windows 11 timing, I had to configure it in Windows mode, it was off by two hours. The BIOS runs on a 24-hour cycle, but Windows doesn’t. Still, the settings remained, no extra steps needed. That covers all defaults from last night too. No problems with the Overclocked version either. Sleep, I can’t help. I don’t sleep my rigs. All or nothing haha XD
