def now
  ::Time.now
end

.now_provider=(block) ⇒ Object

Overrides the implementation of ‘#now with the provided callable.

Overriding the method ‘#now` instead of indirectly calling `block` removes one level of method call overhead.

Parameters:

  • block (Proc) —

    block that returns a ‘Time` object representing the current wall time
