org.jfree.chart.date.SerialDate

An abstract class that defines our requirements for manipulating dates, without tying down a particular implementation.

Requirement 1 : match at least what Excel does for dates; Requirement 2 : the date represented by the class is immutable;

Why not just use java.util.Date? We will, when it makes sense. At times, java.util.Date can be *too* precise - it represents an instant in time, accurate to 1/1000th of a second (with the date itself depending on the time-zone). Sometimes we just want to represent a particular day (e.g. 21 January 2015) without concerning ourselves about the time of day, or the time-zone, or anything else. That's what we've defined SerialDate for.

You can call getInstance() to get a concrete subclass of SerialDate, without worrying about the exact implementation. @author David Gilbert
