I have a digital clock that runs from the 60 hertz power.  I have 
noticed several times that TVA power can gain time up to 15 seconds 
compared to UTC.  Takes a few weeks.

I also did a stability test using a rubidium and dividers and I showed 
about a +/- 0.03 hertz deviation over one hour, during a 24 hour test 

Maybe we all should run a power line test at the same time and we should 
be able to see who is leading and lagging !
