That thing that happens on Sunday after a relaxing weekend when you look at the clock and it says 6pm, and you look again 5 minutes later and it says 9pm. Usually accompanied by an entire weekend's ration of homework/preparation for the week that you haven't yet started.

"Okay, it's 6:03. I need to start my lesson plans for the week... just going to watch TV until the commercial... wait... now it's 9:05? oh SNAP! What just happened?"
