Re: a human-eye date format everyone can love

I would shorten the time zone. As we have discussed -05 and -0500 are
equivalents.

About the space before the time zone: When I first wrote code which
generates readable iso dates I thought that putting a space before Z makes
the date more readable. But when I started regularly *using* iso dates the
space became inconvenient.
2002-06-24 10:36:04 Z
2002-06-24 10:36:04Z

So I recommend to use the shorter
2002-06-24 10:36:04-05 (Mon 24 Jun)
instead of the longer
2002-06-24 10:36:04 -0500 (Mon 24 Jun)

Anyhow, IMO the new "rfc" is far better then the current format, the
parantheses was a very nice idea.
