The comments made by my colleague, Mr. Wilson, confirm what I have just said. If we control when the motion is filed, and if members of the committee do not receive it in time because of technical reasons...
In my humble opinion, I believe that it would be wise to set the deadline for filing a motion no later than 6:00 p.m., but to allow for a full 24 hours to go by from the time of filing to consideration in committee. Whether problems arise or not, nobody will be taken by surprise. There is not a huge difference in terms of hours.
