Then I would go for a cron entry at the earliest time you want the
script to be run (say 6:00 AM) which does something like

0 6 * * * root sleep $(( $RANDOM % max_gap )) ; your_command

Where max_gap is the number of seconds corresponding to the latest time
you want your script to be run - 6:00 AM.
