Question execution time / runtime -- bash script please help!

Hello,

I'm running a bash script and I'd like to get more accurate a runtime information then now.

So far I've been using this method:

Code:
STARTM=`date -u "+%s"`
.........
*script function....
.........
STOPM=`date -u "+%s"`
RUNTIMEM=`expr $STOPM - $STARTM`
if (($RUNTIMEM>59)); then
TTIMEM=`printf "%dm%ds\n" $((RUNTIMEM/60%60)) $((RUNTIMEM%60))`
else
TTIMEM=`printf "%ds\n" $((RUNTIMEM))`
fi

echo "Executing "script function" took: $TTIMEM"

However the script often runs under one second, so the result is 0s.

I'd like it display a more accurate runtime, best 0.015s or 1.123s and so on...

time {} is not really an option.. need the result as var as I pass it to another script...
