/proc/<PID> doesn't seem to have this data. How lame:-(
There are two other ways to attack this: your polling approach (look for
old processes) or just run the commands involved inside a timeout program.
For the polling approach you parse the output of:
ps -o 'pid start_time cmd' ax
which gets you a listing with just pid and start time and command.
Or if you know the pid you can go:
ps -o 'pid start_time cmd' <pid>
For the timeout approach you invoke the process like this:
timeout 10 command args...
for a command that should run for at most 10 seconds.
Timeout's a script you can get here:
