DateTime iso8601 bad handling of dates
by Evan Simpson 01 Dec '05

01 Dec '05

This has been brought up and (rather cavalierly) dismissed before. I challenge anyone to justify the following DateTime behavior: >>> DateTime('2005-01-01').strftime('%Y-%m-%d') '2004-12-31' DateTimes are actually timestamps, and the current implementation assumes that a date in ISO8601 format without a timezone specifier is UTC rather than local. It was asserted, last time this came up, that this is compliant with the ISO8601 spec, but my own research shows this to be false. If someone can point me to a truly authoritative source that supports the current behavior, I would appreciate it, but that would not change the fact that the manifested behavior is *broken*. This is a simple two-line fix, folks. I've already done it on my production systems. Cheers, Evan @ 4-am

They aren't well-enough "battle tested" to make Andrew's point invalid, I think (there *are* no "large" ZODB-based Zope3 sites which have undergone generational upgrades). Frankly, anything which attempts to "fix pickles" in-place smells bad to me. "Dump and reload" is how the RDBMS world handles this kind of problem, and it isn't because they don't have smart folks working on them.

Re: [CMF-checkins] SVN: CMF/trunk/ CMFSetup is dead. Long live GenericSetup!
by Chris Withers 01 Dec '05

I'm probably missing something, hence my asking. If GenericSetup is generic, why is it in the CMF repository? Sure, bundle it with CMF, like BTreeFolder2 used to be, but why not also release it seperately and have it in its own repo? cheers, Chris Yvo Schubbe wrote: > Log message for revision 40429: > CMFSetup is dead.
