Sensible.  FWIW, having just sifted through a list of over 1.5 million
"Dates" returned from distinct IP addresses in HTTP headers requests,
only 308 of them  had the format laid out differently from the one
shown below:

          "Thu, 16 Sep 2004 21:00:36 GMT"

Of those 308, 72 of them played around with different formats for GMT
such as -0300, GMT+0200. A bunch more left out the comma after the
weekday.

Bottom line is that the dates in HTTP headers don't seem to be
internationalized on web servers (either that, or there are
very few internationalized servers). So, if one was to rigourously
stick with the format used by Apache, you'd catch 99.98% of the
cases. The remaining, well, I'd say you just wouldn't report a
parseable date/time, that's all.

Agreed.

Great!
