Hi

There was a project UUID in apache can create TimeUUID , url is:
http://commons.apache.org/sandbox/id/uuid.html

please refer to javadoc:
http://commons.apache.org/sandbox/id/apidocs/org/apache/commons/id/uuid/UUID.html

code like:

*UUID<http://commons.apache.org/sandbox/id/apidocs/org/apache/commons/id/uuid/UUID.html>
uuid
= org.apache.commons.id.uuid.UUID.timeUUID<http://commons.apache.org/sandbox/id/apidocs/org/apache/commons/id/uuid/UUID.html#timeUUID()>
*()


thanks
-Santal
