I think you're limited to 1 minute granularity.  But if you want to run something at a specific second (ie: 13 seconds after the minute), you could modify the script to sleep for 13 seconds before running and run it on the minute, or prepend a sleep in the cron entry itself:

* * * * * sleep 13; touch /tmp/foo

If life gives you lemons, keep them-- because hey.. free lemons.
