When your users are scattered across the internet, there *is* no single cnventional local time which will not surprise some / most of them; the timezone of the location in which the server happens to reside is completely irrelevant to a user. Zope has therefore adopted the convention that "local time" in Zope is GMT for ISO-spelled strings (the "slash" form uses the OS-supplied default timezone, again for backward-compatibility; the ISO spelling was added later). >>> I strongly disagreed with the argument for that change >>> (http://www.zope.org/Collectors/Zope/2109), because it broke the >>> semantics of the class, based on long-established use in Zope: datetime >>> strings which used ISO notation, but provided no explicit timezone, were >>> assigned 'GMT+0' as the timezone. >> Totally agreed. > > However if we must preserve this bug for backwards compatibility then we > must. (This bugfix would not change the interpretation of existing pickles).
