tests fail in year 2038 #245
Description
BUG/PROBLEM REPORT / FEATURE REQUEST
What I did:
While working on reproducible builds for openSUSE, I found that
our python-ZEO 6.1 package fails tests when run after 2038-01-19
with qemu-kvm -rtc base=2038-01-20T12:00:00
What I expect to happen:
Tests should continue to work for 15+ years.
What actually happened:
