What's the difference between opening and closing shifts? Opening and mid shifts commonly start with a lot of downtime filled in with side-work and time starts to move backwards at that point. With that said, closing shifts tend to be longer, and more hours mean more money.

I don't understand the phrase "and time starts to move backwards at that point" - Suppose you arrive at your office/factory at 8:00AM for the opening shift, how can "time move backwords" from the point 8:00AM? It sounds confusing to me. What does it mean?
