[Tinyos-help] How can I measure computation time in Tossim properly ?

[Daehee Kim]

Hi. Everyone

How can I measure computation time in Tossim properly ?
As I mentioned followings, the time difference between computations was same
although the computation 100^3.

I used "LocalTime.get()" to get time.
Are there any settings that I have to reconfigure in TinyOS to measure
computation time properly ?

Thanks.
Danny
