[Zope3-dev] Copyright/license of 'datetime' package in Zope3/src?

[Phillip J. Eby]

Just a quick question...  I'm planning to distribute the 'datetime' package 
in PEAK for "backward" compatibility with Python 2.2, and I'd like to 
properly credit the copyright and license in my docs.  Is it under PSF or 
ZPL, and who's the copyright holder?  I assume the author is Tim Peters, 
and the copyright and license are PSF, but there is one file, 
'datetime/tests/__init__.py' that claims to be ZPL, so it's a bit 
confusing.  Thanks.
