OK, I'll put #1 in as a feature request.  I'd say that there perhaps 
were both CDR time counters available in the report - the epoch 
timestamp that the channel was created (ast_chan_alloc?) and then the 
epoch timestamp when the call was answered (or bridged?  I don't know 
exactly what the internal data structure in the CDR looks like in the 
code.)

On #2: OK, I understand.  I was looking at it as a descending timer 
(in ms or something) since I had my AbsoluteTimeout set very very 
high on the test call that I was looking at, though I should have 
recognized it as UNIX seconds.  "real time" termination marker makes 
sense.
