Howto Monitor elapsed time in a shell script

I have a script that creates a backup for me. I would like to keep track of its progress, so I would like to see, every second (or so), the time elapsed and the size of the backup file. I manage to get the size of the backup file, but I cannot get the elapsed time to work.

This is what i have:

1. To create the backup:

every 1 sys_echosize $tarfile &
tar cfz $tarfile .
kill $every_pid

2. The "every" script performs a cmd every few seconds:

while true ; do
sleep $t

3. The "sys_echosize" is as follows:

echo -e -n " " `du -h $1` "\r"

Nice, isn't it?!?
But not finished, as I would like to have the time elapsed of the tar command...

Any help would be appreciated!!!

Thanks! I did, but could not get it working in the above scripts...
Currently, the output is something like:

640M /tmp/fullhd.tgz

And I would like it to be something like (after 4.5 minutes backupping):

640M /tmp/fullhd.tgz (4m:30s)

and (after 5 minutes of backupping):

695M /tmp/fullhd.tgz (5m:00s)

A clou?!?
