The W3C specification is not at all specific about how to write the #Date
line. There are at least three different date formats used in that one
document and a wide amount of disagreement between different
implimentations. Microsoft always uses YYYY-MM-DD with everything digits.
WebSTAR uses #Start-Date instead of #Date and MM/DD/YY with digits in the
US but DD/MM/YY in export versions. Others use DD-MMM-YYYY with the month
in abreveated text.
I would need to see an example from your log file to know specificaly
what is going wrong with Analog.

as a searing indictment of the narrow-minded binary counting system.
