Try:
bgn=$(date +%s)
sleep 7
end=$(date +%s)
echo "elapsed seconds = " $(( end - bgn ))
Play with values other than '7'.
To actually use in a script, replace the sleep command by whatever you
want to measure the elapsed time for.
Expressing elapsed time as HH:MM:SS requires a little more work. To
write that script, use / for divide operator and % for remainder operator,
like in C.
