The have changed the pause feature over the years, but last year I could pause the feed when they called our class up, and restart it after I'd serviced the car post run .... roughly 90 mins to 2 hours in total. Not sure if you could pause the entire day and have it smoothly pick back up.
Not certain if this works for everyone but: If I want to watch the show in the evening, I begin the feed early in the day. As long as the race is still running, I'm able to "rewind" all the way back to when I logged onto the event.
This only seems to work if the event is still running. HTH
