Balancing previous 1 rating by @Ingo.
To Ingo: You said module's documentation is okay, one feature you use works okay, and other features you don't use. Why only 1 star then?
This module is a worthy alternative to Test::MockTime. It offers extra features such as working across forks, mocking Time::HiRes (eventually), and speeding/slowing down time.
