The TV guide schedule beginning November 1 has altered the listed times to 2,5,8,11...
I hope this is just an anomaly and that the 3,6,9,12... pattern resumes.
It's probably related to the transition from Daylight/Summer to Standard time, since those timezones that observe it switch at 3am on 1 Nov.: the clocks will go from 2:59am one minute, and 2am the next.
Dough!
