Thanks for your reply, JP.
You're right that it looks like a bug in xmlrpclib itself; however, it only
looks like it's a bug in Python 2.4's version of xmlrpclib; version Python
2.5 has a slightly different xmlrpclib.py that does not exhibit this
behaviour; using your example:
Python 2.5 (r25:51908, Oct 6 2006, 15:22:41)
[GCC 4.1.2 20060928 (prerelease) (Ubuntu 4.1.1-13ubuntu4)] on linux2

>>> import xmlrpclib
>>> d1 = xmlrpclib.DateTime()
<DateTime '20070209T13:02:31' at b7d4896c>
>>> s = xmlrpclib.dumps((d1,))
>>> d2 = xmlrpclib.loads(s)
<DateTime '20070209T13:02:31' at b7d48e2c>
So obviously someone noticed that 2.4's was buggy from a round-trip
point-of-view and corrected it for 2.5. Not sure if that means that they will
be unreceptive to patching 2.4.
It also looks like one can just drop 2.5's xmlrpclib.py into a 2.4 tree and
run compileall.py and the odd behaviour disappears.
Having Twisted work around this problem would be a Good Thing, however. I'll
file a bug report.
