To test the readiness of Yocto stack for Y2038 we run qemu virtual machines with RTC set to some day in 2040. This causes many of python's tests to fail on both 32 bit and 64 bit systems: the reason is that test certificate expiry dates are set to 2037 or so by Lib/test/make_ssl_certs.py:

startdate = "20180829142316Z"
enddate = "20371028142316Z"

I would propose to set the expiry date to far enough in the future that it won't have to be tweaked in our lifetimes: this way real Y2038 issues in python (or in things it depends on) can be exposed and fixed (it's well possible there are none, but that needs confirmation too).

Failures seen:

6 tests failed:
test_asyncio test_httplib test_imaplib test_poplib test_ssl
test_urllib2_localnet

If there's agreement on this, I can prepare the patch.
