All Implemented Interfaces:

Serializable, Cloneable, Iterable<Outage>, Collection<Outage>, List<Outage>, RandomAccess

public class OutageSvcTimesList
extends ArrayList<Outage>

 This contains a list of service lost/regained set/pair.

  Also maintains the outage/down time each time it is calculated and the time
  from which this was calculated - this is done so when the view outage time for
  a window is calculated, the same calculations are not done on the node multiple
  times
