I have about 140 witty pi's!!! and I use this shedule on all witty pi 4's:
BEGIN 2022-10-11 06:30:00
END 2033-09-30 22:30:00
ON H16
OFF H8
however I now have 10 that have started to not do this:
They will start correctly the next day but then will set the shutdown time as a minute before the startup time on that date, so they will not shutdown and will not restart, it seems to be spreading!!! Any ideas

set the shutdown time as a minute before the startup time on that date
That seems to be the behavior of "schedule revising", as described here: https://www.uugear.com/forums/technial-support-discussion/witty-pi-4-about-schedule-revising/#post-8
It is designed to avoid breaking the schedule, when the schedule is interrupted.
Like you said, it set the shutdown time as a minute before the startup time on that date. That means it should shutdown and then startup at the scheduled time. If it was not what happened, you need to check the wittyPi.log and find out why.
Why the schedule was interruptted is also a question that needs to find out the answer. I have no clue with the provided information.

System starts up because the input voltage reaches the restore voltage.
If you are powering the device via USB-C connector, you need to clear the low voltage threshold and the restore voltage threshold. They are not useful for your use case, and they might cause unexpected startup, which interrupts the schedule.
If the interruption happens very close to expected startup time, the schedule revising will not work as expected and it could set the shutdown time in the pass. You can see it actually happened in the log you provided.

It looks like removing the recovery voltage worked, one of the systems has started behaving itself, I'll change the others and report back if they don't start working properly again
