public interface TargetDependIncreasing
extends Increasing

An interface denoting that this Value implementation has a value that increases with time. More importantly, this value knows how to calculate the remaining time it will take until a certain value is reached. This time can be queried and used for e.g. scheduling purposes.
This interface should be implemented by target depending parameters.

                      Number until)

Calculates the remaining time in ms till this parameter reaches the argument value (increasing from lower values). For a time query this is simply the difference between the argument value and the current time.
