No, if you want to track the jobs you'll need to configure a script wrapper to log the start/finish time as well as any output.
eg.
Code:
LOG=/var/log/myjobs.log
JOB=$1
echo "Start $JOB: $(date <pick-your-formatting>)" >> $LOG
$JOB >> $LOG 2>&1
echo "End $JOB: $(date <pick-your-formatting>)" >> $LOG
