Microsoft calls that field various things in various places: Elapsed
Time, Processing Time, Time Taken, Time for Processing.
All times in the Windows programer API that are finer than seconds are in
milliseconds (1/1000ths), so many people assume that that is what the
logs must contain. I've never seen Microsoft actualy say what units the
field in the logs are in, although some people such as
<http://www.steds.org/Docs/ms_iis/log_format.htm> say that they are
milliseconds and also claim to be quoting Microsoft.
The number isn't always acurate either, see
<http://support.microsoft.com/support/kb/articles/Q197/8/17.ASP> and
<http://support.microsoft.com/support/kb/articles/Q191/2/56.ASP>.
Microsoft does reference the W3C draft in a few places, notably in
<http://support.microsoft.com/support/ServiceWare/Iis/iis40/3LNN1ASP.ASP>
where they are defending their use of GMT instead of local time by saying
that that is what W3C specifies.
Anyhow, I got that they are in 1/100ths through emperical testing.
Summary produces a modem speed report based on the TIME-TAKEN number and
I get a near perfect match to the modem speed distribution observed on
other sites when I assume the numbers are 1/100ths of seconds.
You may need a Microsoft developer account to access the Microsoft
support URLs above, I'm not sure.

Dr. Seuss books . . . can be read and enjoyed on several levels. For
example, 'One Fish Two Fish, Red Fish Blue Fish' can be deconstructed
as a searing indictment of the narrow-minded binary counting system.
