When I want to:

- know if a time exists satisfying a condition

with each(), I can call Enumerabe.detect { cond...}

with each_before(stop_time) I have to implement Enumeralbe.detect myself

- get all times within a period

with each(), I can call Enumerable.find_all { cond.. }

with each_before(stop_time) I have to implement Enumerable.find_all
myself

...


You can build any kind of each_x_y() you want, but you don't get the
utilities from the Enumerable mixin when you do so.
