[issue12198] zipfile.py:1047: DeprecationWarning: 'H' format requires 0 <= number <= 65535

On 2.7, your example raises an error:

Traceback (most recent call last):
  File "a.py", line 7, in <module>
    z.write("a", "a")
  File "/home/petri/tmp/cpython/cpython/Lib/zipfile.py", line 1071, in write
    self.fp.write(zinfo.FileHeader())
  File "/home/petri/tmp/cpython/cpython/Lib/zipfile.py", line 348, in FileHeader
    len(filename), len(extra))
struct.error: ushort format requires 0 <= number <= USHRT_MAX

I doubt this can be fixed in 2.6 anymore, as it's in security fix only -mode.

What comes to the error on 2.7, it could be better. If zip files simply don't support dates before 1980, an error describing this could be raised. Another possibility would be to clamp too old dates to 1980.
