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?
