Issues with benchmark class

[eluser]neen[/eluser]
I want to shift the decimal on elapsed_time() two places to the right, so I can output in MS (ie: 0.065 s to 65 ms). I'm using the following code:

Code:

<? $this->benchmark->elapsed_time() * 100 ?>

The problem is, it outputs (string) "{elapsed_time}" and then multiplies that by 100, which ends up equal to 0.

Now, I can always do this:

Code:

<?= number_format($this->benchmark->elapsed_time('total_execution_time_start', 'total_execution_time_end') * 1000)  ?>

Now the issue when I do that is very minor, but for some strange reason, 'total_execution_time_end' ends up before the benchmark for the current controller with profiler enabled...any ideas why this happens? Just curious..
