Zope 2.7.6 Python 2.4.1 (and yes, I know I am jumping the gun a bit)
The problem appears to be in the parse component --
Consider a test script:
for y in range(1995,2005): for d in (1, 3, 13, 25,): for m in (1,4,5,6,): dd = '%d-%02d-%02d' % (y,m,d,) ee = '%d/%d/%d' % (m, d, y) D = DateTime(dd) E = DateTime(ee) print dd, D.strftime('%Y-%m-%d') print ee, E.strftime('%Y-%m-%d') return printed
In all cases, each of the dates shoudl be the same. As can be seen, for dates sourced from a string of the form
1995-04-25
the resulatant date is off by one day
1995-04-24
The problem is not seen with Zope 2.6.4 running with Python 2.3.5.
A quick diff shows tht there are many changes between 2.6 and 2.7. Anyone else seen this problem?

Yes it happes to me also every time I use strftime, so I stopped using it. Someone posted a patch to fix this in this list not a long ago. I think this is a problem of interpretation on how the default behavior should be as these dates do not have any Timezone information. But I would prefer zope to work the same as python itself, that works as expected. Luiz Fernando B. Ribeiro
