[issue6090] zipfile: Bad error message when zipping a with timestamp before 1980

[Petri Lehtinen]

Petri Lehtinen <petri at digip.org> added the comment:

Retitled to reflect that the error message should be enhanced.

Attached a patch for 2.7 that raises ValueError for timestamps before 1980, documents that 1980 or later is required, and adds some tests.
