tests fail on 32 bit platforms

The root cause is: strftime() return long int. And long size is 32 bits in 32 bit system, 64 bits in 64 bit platform.

I'd suggest setting all these timestamps to "2038-01-18T21:14:08Z" as the last possible moment supported by 32-bit systems.

>>> from keystoneclient.openstack.common import timeutils
>>> import sys
>>> timeutils.parse_isotime('2038-01-18T21:14:08Z').strftime('%s')
'-1'
>>> timeutils.parse_isotime('2038-01-18T21:14:08Z').strftime('%s')
'2147483647'
>>> sys.maxint
2147483647
>>> pow(2, 31) - 1
2147483647L

So, do you mean:

if isotime >= 2038-2038-01-18T21:14:08Z:
    return 2147483647
else:
    return parse().strftime()

No, the test certs were updated to a date far in the future because they expired and tests started failing. I'm suggesting that the certs simply be revised again to expire on 2038-01-18T21:14:08Z.

Sorry, terrible copy paste fails above on my part.

The correct time that will work on 32-bit systems is:

  2038-01-18T21:14:07Z

The first time that will fail on 32-bit systems is:

    2038-01-18T21:14:08Z

    Set example timestamps to 2038-01-18T21:14:07Z

    This timestamp is the last possible moment that can be represented on
    32-bit systems as an integer.

    As a consequence of revising the JSON examples, the corresponding PEM
    files must be re-generated as well.
