Each committee varies on this issue. One way is to ensure that the notices of motions are in, say, by four at the latest and distributed by six at the latest. Anything later than six would not meet the 24 hours.
Sometimes the motions are not translated and sometimes they're not correct, so they require a bit of fiddling. They may not be sent to the members, though, till seven or eight o'clock at night. If you have a nine o'clock meeting the next day, in theory that meets 24 hours because it's one night, but a lot of members' offices are not open at eight o'clock at night. So it means your staff would come in at 8:30 and have a motion facing him or her.
