public class TimeStamp
extends java.lang.Object

This class encapsulates the notion of a timestamp as in rfc2030. Logically it is the number of seconds since the beginning of the centure (in UTC time). It is represented as an 8 byte array, the first four bytes representing seconds and the next 4 bytes representing second fractions.

Field Summary

static TimeStamp

zero The timestamp corresponding to the beginning of the century.

Constructor Summary

TimeStamp()
This constructs a timestamp initialized with the current date.

TimeStamp(byte[] data)
This constructs a timestamp starting from an eight byte array.

TimeStamp(java.util.Date date)
This constructs a timestamp initialized with a given date.

Method Summary

boolean	equals(TimeStamp ts) Checks for equality of two timestamps.
byte[]	getData() Returns the eight byte array associated to a timestamp.
java.util.Date	getTime() Returns the date associated to a timestamp.
java.lang.String	toString() DOCUMENT ME!
