Title:
  Memcached token backend should work with any timezone

Status in OpenStack Identity (Keystone):
  Fix Released
Status in Keystone grizzly series:
  Won't Fix

Bug description:
  In configuration document, it looks like following configuration are
  required with memcache token backend.

  - Memcached server's timezone is set to UTC.
  - Timezone of both Memcached and Keystone server should be same.
  So Keystone server's timezone is  also set to UTC.

  http://docs.openstack.org/developer/keystone/configuration.html
  #memcached-and-system-time

  I guess this limitation is caused by incorrect expiration time is set
  when tokens are generated.

  backends/memcache.py call utils.unixtime() and it calls time.mktime().
  time.mktime() return localtime, not UTC, so its value depends on time zone.

  In my tests, if keystone server runs with UTC + N (N>=1), token
  authorization failed.

  # run keystone server with UTC+1
  > env TZ='UTC-1' tools/with_venv.sh bin/keystone-all
  # get token
  > env TZ=UTC tools/with_venv.sh keystone .. token-get
