Detecting stuck process

With ps you can display the start time of a process.
The better way of doing it probably having your process write the start
time to a file and have your check script compare the start time with
current time.

Subject: Detecting stuck process

How can I test, in a bash script, to see whether there is a
process running for say more than 30 seconds, and if so then
execute appropriate action?

I currently have a cron job that runs every X minutes that
runs a script (which restarts the stuck process), but
technically I only need to run this script if a certain
process gets stuck.  How can I pull the info from 'top' and
see if it's more than 30 seconds in the TIME column, and
only then run the rest of my script?

Thanks,

Chris
