Nope, Jython doesn't have ``property()``.  That is a CPython 2.2
feature and thus is not in Jython since it only supports CPython 2.1
code (I think).

Thanks!  Glad you think so!

So here is the deal: ``property()`` is not critical for ``strptime()``
to work.  I put that in the code so as to make find out locale info
lazy.  You can rip out the ``property()`` assignments and just always
do the calculations in the ``__init__()`` method.  So, you could
change the line::

    f_weekday = property(__get_f_weekday, __set_nothing,
                        doc="Full weekday names")

to::

    f_weekday = self.__get_f_weekday()

in ``__init__()``; do this for all property values.  That is not the
best way to do the backport, but it will do the trick.

If you do decide to do a backport, make sure you grab the latest code
from CVS; all of my fixes have gone straight there and there have been
several fixes since the Cookbook came out.

If  you can muster some more people to clamor for this (just reply to
this post and make sure you cc: it to me), I would be willing to do
the backport to Jython myself and put it up on the Cookbook web site
as the current version of the recipe.

Hope that helps.

P.S.: Thanks should go to Laura Creighton of AB Strakt of forwarding
this post to me.

P.P.S.: Thanks Laura for always being a supporter of my strptime
module.  First person to ever thank me for that recipe.  If I had
never heard from anyone I probably would not have bothered to put  as
much effort as I did into the darn thing after the first version.
