Among my time nut toys is a Consumer grade GPS clock and a similar WWVB
clock. The WWVB clock consistently runs about 0.2 seconds ahead of the GPS
one. I know no one can say why without knowing the particulars of the two
clock's circuits. Just thought I'd post it for what it's worth.

===================================
Max,
I see similar things here. I've always put it down to relatively poor
circuitry in the radio clock, which is why I built my NTP-controlled wall
clock!

One radio clock is below. That particular MSF clock is actually not too
bad - visibly it's in sync with the NTP clock (which itself is within a few
microseconds of GPS time).
