DO NOT MERGE Fix bug regarding the comparator sorts Alarms into increasing time order.

The comparator used variable "when" in IncreasingTimeOrder class.
variable "when" means "elapsed time" or "real time"(RTC) and these types have different unit of time.
so, I recommend that you use a "whenElapsed" which has the equal unit of time as its default value.
