There is no separate at daemon. Cron takes care of cron jobs as well
as at jobs. From the cron manpage:

"cron executes commands at specified dates and times. Regularly
scheduled commands can be specified according to instructions found
in crontab files in the directory /var/spool/cron/crontabs. Users can
submit their own crontab file via the crontab(1) command. Commands
that are to be executed only once can be submitted using the at(1)
Cron also takes care of the execution of jobs issued by at(1) that
are found in /usr/spool/at/. Cron simply runs the AT job as if there
were an "sh at-job" as a cron job at the appropriate time under the
user-id of the owner of the script. The script takes care of the
rest. See at(1) for the details."
