What time is it anyway?

This morning Eric and Charles were up pretty early. Charles snuck into our bedroom and asked if he and Eric could play Lego Star Wars. I thought it was 6:00 so I said yes. A few minutes later Charles snuck back into our bedroom needing new batteries for the controller. When I got up to put them in it was a few minutes after 5:00. What? My sleep filled eyes misread the alarm clock the first time. When I asked Eric why they were up at 5:00 he denied it explaining that it wasn't 5:00 when they got out of bed. He couldn't sleep. So at 4:00 he went to another bed to snuggle. Then Charles woke up and joined him. He further explained that it was 4:48, not 5:00 when he and Charles got up this morning.
