Set up a cron job to periodically run a script that will perform the
action you want. The script should check the database for any work to
do at this time, and if there is nothing to do then it just exits.
Adjust the frequency of the cron job so that it matches the accuracy of
recording start time you require - say, every 5 minutes.

This way, no-one else has to be given permissions to add "at" commands
or mess with the hardware.
