Timing with 20Mhz? about mightycore

[MCUdude]

I'll have a look at it when I get home. Meanwhile, please try with the 16 MHz option and see if this drifts to. I guess the problem is the millis() function. Have you also tried swaping it with another 20 MHz crystal?

Thanks, Hans. Tonight I'll try it with a 16mhz crystal. Several clocks
built with the identical configuration have the same issue, so it's not the
crystal. I agree that it appears to be related to the millis() function.

I'll let you know later after I swap a 16mhz crystal and change the
firmware.

Regards,
Mitch

Still waiting to test. We're moving, so it will be another few days. Thanks.

Sorry. I don't think this is an issue with the core.
