Well, I'm not going to do your work.

Your heartbeat probably is 600 and your step 300
(that's pretty standard)

If you type "date +%s" on your command line, you'll
Get the number of seconds that have passed since 
01-01-1970 00:00:00. That's called an epoch timestamp.

Round it to the nearest 300 seconds border and use that
timestamp to update your database.

timestamp=`date +%s | awk '{print $1-($1%300)}'`
rrdtool update file.rrd $timestamp:$value1:$value2
