org.xmlBlaster.util.Timestamp

High performing timestamp class, time elapsed since 1970, the nanos are simulated as a unique counter.
The counter is rewound on any millisecond step.
Timestamp objects are immutable - a Timstamp can not be changed once it is created.
Guarantees that any created Timestamp instance is unique in the current Java Virtual Machine (and Classloader).

Fails only if

a CPU can create more than 999999 Timestamp instances per millisecond
In ~ 288 years when Long.MAX_VALUE = 9223372036854775807 overflows (current value is 1013338358124000008)

A typical output is:

toString()=2002-02-10 11:57:51.804000001
getTimestamp()=1013338671804000001
getMillis()=1013338671804
getMillisOnly()=804
getNanosOnly()=804000001

Performance hints (600 MHz Intel PC, Linux 2.4.10, JDK 1.3.1):

new Timestamp() 1.2 micro seconds
toString() 55 micro seconds the first time, further access 0.1 micro seconds
valueOf() 19 micro seconds
toXml("", false) 16 micro seconds
toXml("", true) 17 micro seconds

XML representation:

 <timestamp nanos='1013346248150000001'> 2002-02-10 14:04:08.150000001 </timestamp>

 <timestamp nanos='1013346248150000001'/>
