java.util.Date

com.ergotech.util.NTPDate

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Comparable<java.util.Date>

public class NTPDate
extends java.util.Date

This class creates a Date. If an NTPClient is running, it will update this class with the time from the server and so this class will accurately represent the true NTP time. If no NTP client is running this will just return the system time. This has no NTP dependencies and so can be used in any system.
