ZoneEqualityComparer class

Equality comparer for time zones, comparing specific aspects of the zone intervals within a time zone for a specific interval of the time line.

The default behaviour of this comparator is to consider two time zones to be equal if they share the same wall offsets at all points within a given time interval, regardless of other aspects of each ZoneInterval within the two time zones. This behaviour can be changed using the withOptions method.
