Subject: [PATCH] Handle OverflowError on parsing timestamps as
 BadTimeSignature
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

on 32bit platforms the test TestTimestampSigner::test_malformed_future_timestamp
causes an OverflowError. Catch this and raise it as BadTimeSignature
