Great detective work! I assumed the watershed time would have this kind of
characteristic.
My timezone is Eastern Daylight, BTW.
Dave Siktberg seems to have narrowed it down to 2006-05-12 21:25.
In what timezone? It sound like that could equate to Sat May 13

I've taken a break to play with some PG logging on my development machine

Any idea what could cause this? How to fix it? A year ago I did not

My link to aolserver documentation ( www.aolserver.com/docs/devel/tcl/api/ )
no longer works - redirects to SourceForge which complains Invalid

the docs and reference them locally.)
Thanks! Dave

Development of my first site is well underway, and I am starting to think
about production configuration issues. What's the best way to structure
things so I can isolate development work and the testing thereof from the
production system? To do orderly moveups from development to production?
I'm a relative newbie to AOLServer, but a developer for many years. All the
evidence I see (developing our website, lurking on this listserve and
others, reading Phil Greenspun's book, talking with aD developers, watching
people develop on other platforms) says to me this is a good choice for
