Traditionally it has been the practice of this committee that, should a motion arise during the discussion of committee work, the member hands it in to the clerk and, as of 9 o'clock in the morning, the 48 hours starts ticking. Technically, if you hand it in at 10 o'clock, then you have to deal with it on Thursday morning at 10 o'clock.
We usually deal with motions at the end of the committee, so it's part and parcel of the same thing. Let's not nitpick on 10 o'clock, 9:30, or 10:30.
