ps -fo etime -p pid_of_your_process

This will show you the elapsed time as

DD-HH:MM:SS

so you can easily calculate the start time.

I assume you know how to get the PID of a running process?

Take the second column of

ps -ef | grep programname

I just hope you do know the name of your program (at least part of it) 'coz I will not be able to help you there.

The program is called "saguaro", so is the pid=15128?

No, that's the PID of your "grep" search.

The PID is 12557

Can we  just use one line or a batch file to get it?

You asked for it!

Save the following script in a file named e.g. pstime, issue "chmod +x pstime".

Now determine the id of the process in question (PID) and run the script with

pstime PID

e.g.

pstime 12557

#!/bin/bash
ETIME=$(ps -f -o etime= -p $1)
if [[ -z $ETIME ]]; then
 echo "Process does not exist!"
  else
   echo "Start Time of Process with PID $1 is:"
    if echo $ETIME | grep -q "-" ; then
     date -d "01/01/1970+$(($(date +%s)-$(echo $ETIME | awk -F"[:-]" '{print ($1*86400)+($2*3600)+($3*60)+$4}'))) seconds"
    else
     date -d "01/01/1970+$(($(date +%s)-$(echo $ETIME | awk -F"[:]" '{print ($1*3600)+($2*60)+$3}'))) seconds"
    fi
fi
