Propagation hasn't been the best on VLF either.  I'm a lot closer to
WWVB than he is and my clocks sometimes lose sync for a day or two as
well, but right now they are ally locked on and showing the right time.  
I also have a QRP Labs GPS clock running that is showing the same time
to the second as the WWVB disciplined clocks.  I'd bet it's either RFI
from a noise source in the house or neighbor's house if close enough or
just poor summer propagation on VLF.

He may have just recently added a local RFI source to his home.
There are some noisy switching supplies out there on consumer devices.
One clock I have has an LED display and it shuts the LEDs off at 2am local
time for 10 minutes to allow syncing to WWV.

I had a friend ask me if something has happened to WWV's time
transmissions. He says the clocks in his home and his watch are
no longer syncing correctly. I think these are syncing to
signals at about 60KHz.

Does anyone know anything about this?
