The Mac Studio first screen shows the wrong date and day

When I start my Mac Studio, the first screen shows the wrong date and day. It always says Thursday, April 1st, and the time is 00:00.

I enter my login password, and the date and time update as expected.

After working normally, I turn off the computer, and this problem recurs, sometimes on and sometimes off.

Has anyone had the same problem?

How was it solved?

I know that the Mac Studio doesn't have a PRAM battery, so it can't be replaced.

Is this true?

Thanks
