A comment on Windows feature that resets system clocks based on random data is wreaking havoc.

I sometimes experience a similar issue with my linux laptop where time jumps to the year 2077 when waking up from sleep. My guess is that it is a hardware glitch as it doesn't happen often, but when it does it is quite impactful.

One of the annoying consequences is that some parts of the system decide to clean up "old" data. Surely data that has been stale for 50 years can be deleted, right? I cannot imagine the impact of something similar happening on a production server.

I had that with old mac os versions. Fun to finally know why it happened

Coincidence?

Nice spot.

Perhaps something that is meant to add a delta to a timestamp accidentally adds 2 timestamps together.

How is the hardware clock connected? It it is something serial it could be an offset by 1 bit.

If it's an x86 laptop, it will be compatible with the MC146818 chip found in the original IBM AT, and return the time in BCD format as yyyy/mm/dd hh/mm/ss.

On modern systems the simulated MC146818 is part of the chipset.
