Comment 4 for bug 142784

"%Z" no longer does anything, on 2.9 or trunk:

>>> import DateTime
>>> d = DateTime.DateTime().toZone('US/Pacific')
>>> d.strftime('%H:%M %Z')
'18:15 '

See also https://bugs.launchpad.net/zope2/+bug/215991 ... people (well, at least two of us) find the implicit conversion to local zone very suprising.
