New submission from Greg Steuck <gnezdo+pythonb...@google.com>:
zipfile.py displays warning when trying to write files timestamped before 1980.
% cat /tmp/a.py
import zipfile
import os
z = zipfile.ZipFile('/tmp/a.zip', 'w')
open("/tmp/a", "w")
os.utime("/tmp/a", (0,0))
z.write("/tmp/a", "a")
% python -V
Python 2.6.5
% uname -mo
x86_64 GNU/Linux
% uname -mor
2.6.32-gg426-generic x86_64 GNU/Linux
% python /tmp/a.py
/usr/lib/python2.6/zipfile.py:1047: DeprecationWarning: struct integer overflow

self.fp.write(zinfo.FileHeader())
/usr/lib/python2.6/zipfile.py:1047: DeprecationWarning: 'H' format requires 0

self.fp.write(zinfo.FileHeader())
/usr/lib/python2.6/zipfile.py:1123: DeprecationWarning: struct integer overflow

self.close()

self.close()
Similar to, but different from http://bugs.python.org/issue1526.
Amaury Forgeot d'Arc says:
The ZIP file format is unable to store dates before 1980. With version 3.2,
your script even raises an exception. Please file this in a different issue.
