Description

When I write a Pattern like this:

Pattern.begin("start").where()
  .followBy("middle0").where().within(Time.second(1))
  .followBy("middle1").where().within(Time.second(2))
  .followBy("middle2").where().within(Time.second(3))

the actual windowTime is the smallest time: 1 second.
If I want having different windowTime in different part of pattern, is there a way to avoid this？
Perhaps I can make "within" become a condition in Pattern, just a thought.
