Oh, I didn't realise you wanted to know what I planned to *do* with the 
information - I thought you were just trying to understand exactly what 
information I need.

So, to answer your question about why I need these timestamps, I have specific 
points throughout the dialplan where I need to know the current (accurate) 
timestamp, in order to collect statistics on the efficiency of different parts of 
the dialplan (basically, how long does *this* section take to complete, how 
long does *that* section take, etc).

These timing values are then combined with similar timestamps from other parts 
of the system (which includes Asterisk, database lookups, and other external 
services) to give an overall measure of the performance of individual parts of 
the whole thing.

Ultimately I do not intend to collect this quantity of data from production 
systems, but on development and test systems I need to be able to spot quickly 
when some part of what FreeSwitch is doing, or anything else we are collecting 
these timestamps from, changes (for better or for worse) in how long the 
processing takes.

Does that answer your question sufficiently to be able to guide to me where I 
can find the current timestamp inside the dialplan?

I didn't realise that this could be a complicated question, but perhaps the 
fact that I didn't find the answer easily indicates that it is?
