The situation Mr. Davies is describing obtains when you're meeting late in the day. For instance, citizenship and immigration used to sit late in the afternoon, sometimes into the early evening. With the 42-hour requirement, that allowed them fewer than two days, and they held fast to the 42 hours. I was clerk of the committee at the time. Where it says 48, it's understood to be the same as the 48 hours’ notice required by the House. It's not truly 48 hours. It's actually.... You need two intervening midnights, deux dodos, two sleeps, however you wish to put it. As long as you have those, if you get the motion by 1600, it could be moved at 0800 two days hence.
