A gem providing "time travel", "time freezing", and "time acceleration" capabilities, making it simple to test time-dependent code. It provides a unified method to mock Time.now, Date.today, and DateTime.now in a single call.
I think the capitalization comes from Ruby types being named in there. In order to clarify that, perhaps something like "a Time instance" could be a wording?
Capitalized the start of two words for consistency throughout the readme.
