[LRUG] Stubbing Time.zone.now

[James Adam]

One thing to bear in mind with Timecop, particularly as your
application grows, is remembering to add a teardown with
Timecop.return in it; if you don't, the reported duration for running
your tests/specs/whatever will be something crazy like 163526.1231
seconds.
