As far as I can tell, VBscript will not time in milliseconds, and the Jscript implementation does not seem to support the GetMilliseconds()
So I end up with just the difference down to seconds, and that's fine when I enable some of my on-Demand script rules because they slow things down a little, but otherwise, kiwi is just too fast to time in seconds. The difference is 0 between start time and end time.
I'm trying to setup average message processing time as one of the statistics as well as logging any messages that take an exessive amount of time and timing individual scripts.
