You are not going crazy. They are generally synched for every 20-22 minutes.
I am sure you have heard the term, “Coming up on a hard break.” That is because the channel is about to send out a code that kicks in the local cable companies commercial computers. I am also sure you have seen a commercial for a second, and then another one starts. And when they end a commercial, and you see another one ending for a second. What you are seeing is the delay between to local “insert” and the commercial running on the network.
The only time they stop those code tones is when there is a 9/11 type of event.
This dates back to the times when they were done with tape players. Back in the day, they did not always have a tone. They sometimes did it all based on time breaks. You could tell when the local cable company had a power outage because the clocks would screw up and the tapes would come on out of synch with the program.
This ends the telecomm history lesson of the day.....
Thank you....I had no clue they did that.
I spent a couple of weeks at a Disney course too....the behind the scenes stuff there just made me angry—and very suspect of how the “sheeple” are manipulated.
