Package ucar.unidata.util

Class Timestamp

java.lang.Object
ucar.unidata.util.Timestamp
All Implemented Interfaces:
Serializable, Comparable
public class Timestamp extends Object implements Comparable, Serializable
A immutable timestamp and related utilities. Hopefully lighter weight than java.util.Date (which is mutable), and we don't have to trip over javasoft/Taligent deprecations.

We are using the java "long millisecs since the epoch" as internal representation. This doesn't roll over until August of 292,278,994.
