don't if you call this a bug, but it's not nice ...
(W2K at least)

The time, that is given for parsing, is only the time that povray
uses to parse, not the time, from parsing start till parsing end ...

You will see this, if you write some loopy, rekursive scripts,
where not /that/ much happens inside the jumps, and the parser
only jumps around in the scripts ...

I had the luck to see this, because the first time I saw this, I was
monitoring my networktraffic, and I have my POV-Files saved on my LAN.
The server is only able to deliver ~4MB/s..

I saw, that in the parsing-stage I saw the network traffic raise up to
32MBit/s, but My WIN-Machine had only a load of 40% ...

After I moved the file to the local harddisk I still have this gap...

The File parses 'bout 30seconds, but in the statistics there are
only 2sec mentioned ...

I think, POV doesn't count the time for I/O, but _I personally_ would prefer,
if this would be done ...

Your observation is simply incorrect.

at least HERE it is ... dunno if it's because of I'm doing an
animation, where the recursion depth increases with time, but:

The script in reality(TM) needs about 12 seconds, but the
per-frame-reports says it needed 0.5secs ...

maybe it's my configuration:

I'll check again, with a single frame when this animation is done,
and after a reboot, but at the moment, it behaves exactly this
way (here)...

You are not by any chance referring to the "CPU time used" line, are you?
