[time-nuts] How do US TV stations disseminate time to DTV converterboxes?

[Greg Burnett]

Bill,

Regarding the indicated time being 1 hour behind as displayed by the ATSC 
converter boxes, so far I'm hearing reports of the same problem in an area 
stretching from Omaha to Denver.  I'm located south of Denver. Regarding 
WWVB, it was coming in OK here again by the time I'd sent my first message. 
At the moment its signal strength is good here again. Please hold-off on any 
speculation regarding the WWVB signal strength issues - I'll look into this 
more carefully the next time its signal strength dips here. (The problem 
might be on my side this time, not on the WWVB side?)
