public class Timeshort
extends java.lang.Object

This class supports working with a short time which may be count in microseconds or any other unit, and its conversion to an absolute timestamp.

• 2016-03-06 Hartmut new: clean() and isCleaned() to set a new pair of absTime_short and absTime.
• 2016-03-06 Hartmut new: set data to private, access only via methods! (Why they were public?)
• 2013-04-30 Hartmut new: sleep(long) as wrapper around Thread.sleep() without Exception.
• 2012-10-14 Hartmut created as util class from well known usage.
