Found this titbit of trivia on the AVSFORUM DTVPAL DVR thread...  can you say "Leapsecond pending flag?"...  I knew 'ya could...

"As part of the ATSC specs, the stations are supposed to send some flags about a month before a change in DST status is supposed to happen (i.e. either come on or turn off). Things have usually gotten very wierd about this time for ATSC tuners that get their time from the stations."
