Timing an operation

[Matthew_S]

Hi all,

I'm fairly new to Bash so if I appear slow that's the reason ;)

I'm trying to write a function that will give me the time it takes to do an
operation and then report to a logfile if it passes or fails.  What I have
so far is;

functionName()
{
        echo Timing the function. >> $LOG
        date
        $FUNCTION
        date
}

but this means I will manually have to calculate the difference between the
two dates.  Can i have something like;

if 
difference between dates <5seconds 
echo fail
fi

??

Thanks in advance,

Matthew.
