Clock with generator

Why do my clocks run about 30 min ahead in about 7-8 hours with generator running

Most AC clocks maintain time off 60 cycle frequency. Generator is running at more than 60 cycles. Get a clock that auto sets time from the air.

That will work too. generator might be able to be adjusted a little closer to correct speed.

I believe that power utilities adjust their output frequency to average 60 Hz (IE: if it runs over for a bit, it will run under to average out), so that clocks will maintain the correct time. Your generator attempts to maintain 60 Hz, and therefore could average under or over over time

If your clocks are run off of a motor then the frequency would effect it.
It shouldn't effect any electronic clocks like in the microware.
Sounds like you have more than one clock that is doing it.
What clocks in the motorhome are you talking about?

The microwave clock & I had a coffee maker plugged in the next morning both clocks had same time which was about 30 min ahead of the time I reset them to correct time as day went on they were both gaining time

Being you have a new Georgetown I would have the generator checked by the dealer under warranty.
It sure sounds like the generator speed is the problem. If you have any accurate voltmeter I would for now check to see what your generator output voltage is. Should be 115-120 volts.
Let us know what you find out.
Good luck

You could be within the correct voltage and have cycles per second still off. I get it at home when running off generator when we lose power. I just know it will be off and reset it as needed

Your clocks are probably synched to a VERY stable household current CYCLE of 60HZ...generators are often unstable in this...but only the clocks notice!
