Overview

THREADING NOTE: The mock Clock is not thread-safe, ||= is not atomic. Thus, thread A could modify @@now between thread B’s comparison of @@now to nil and assignment of @@now to Time.now. The #tick method has a similar issue.

This should generally not be a problem, as tests shouldn’t have a reason to modify the current time concurrently in multiple threads.
