I did this a long time ago, so I don't remember exactly. Typically I would get my nap in on time, but sometimes wouldn't be able to fall asleep for some reason or another.
I think going to sleep 20 minutes late wouldn't be that big of a deal... 1 hour late would probably mess things up considerably.
