On quick inspection, it appears to be crystal controlled. I got as far
as opening it up and will start troubleshooting tomorrow. I have
checked my house power and it appears to be clean. That is not to say
something appears on the line randomly but without any way to capture
that event, I can't sit in front of my oscope hoping to see it.

Now if I could find the schematics for this I would be set.

And do you have some unusual kind of noise on the power lines?

See if they keep time correctly in your office, or in someone else's home.
