I have a digital satellite dish, and was watching a raw PBS feed yesterday, 
where they have a test pattern with a clock zipping by on the bottom. My 
receiver has a clock that is automatically updated from the satellite service, 
and I had them on the screen at the same time, and they differed by 15 
seconds!  This is time coming from the same downlink, one from the clock at 
the uplink site, one from the network. I bet this had some of the local 
stations confused. I forgot to watch my GPS and Oregon Sci  WWV clock. 
My WWV clock seems to have the proper time. I know my OLD GPS, a 
Garmin GPS 50 did not pick up leap seconds, and over the years got more 
and more off time, but I think my newer one has better software.  Interesting.
