shell script for finding average runtime of other script
so I've made a shell script that downloads 6 files in succession from a given url, then deletes them. Now I want to time the script, and the average time it uses by running it ~100 times. My problem is tho, how do I store the time it takes for each run through of the script? I know time writes to standard error, but I'm a total noob when it comes to shell scripting so I couldn't get it to work.
from what I gathered I can use
prog 2>&1
to send it stderr to stdout, but how do I now use the value I want?
what I get when I run my timer is 0.00user 0.01system 0:00.35elapsed and a lot of useless info (at least to me, only interested in elapsed time)
I only want the elapsed time so I can calculate on it later, and I need to send it into a variable so that I can add up 100 runs of the script.
Anyone with a decent clue got any pointers to send me in the right direction?

uudemon
uudemon(4) Kernel Interfaces Manual uudemon(4) NAME
uudemon.admin, uudemon.cleanu, uudemon.hour, uudemon.poll - Administrative shell scripts for polling remote systems, cleaning up spool directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons SYNOPSIS
These shell scripts reside in the following directory: /usr/lib/uucp DESCRIPTION
All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the scripts, remove the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file. This script reports status to the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID (uucpa) or root. This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com- mand is run with the following parameters: -C7, -D7, X2, -o2, -W1. This script runs the uusched and uuxqt daemons in the background. This script polls the systems listed in the /usr/lib/uucp/Poll file. The uudemon.poll script should be scheduled before the uudemon.hour script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script. FILES
Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files. Contains the uucp file. RELATED INFORMATION
Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1) Files: /usr/lib/uucp delim off uudemon(4)
