Having exactly the same problem. Clock and date goes haywire rendering the unit unusable or unreliable. 2092, 2053 and 1970 are just some years I’ve had. It can change in front of your eyes and running programs go on and off. It also affects logs and the system message ‘system idle’ comes up a fair bit.
I believe it coincided with the latest app update but it also happens on the web browser.
I have a replacement from a previous hardware issue so I will try that tomorrow.
Anything to add Ray?
