Recording starts 45 seconds early and stops 45 seconds before end of show

I assume this is the same issue that a bunch of other people have talked about with regards to live sports. Every show now seems to be aired on a delay because of how they send out a signal. However the clock is still on actual time, so a 30 minute show that the cable box thinks starts at 9pm actually starts on the tv at something like 9:01, and ends at 9:31. I don't understand how cox is the only provider that has this issue or why they haven't figured out a fix yet.
