</PRE>

<P>
Represents a value with an error, a unit and a time-stamp.
 
 <p>
 A <code>Measurement</code> object is used for maintaining the tuple of value,
 error, unit and time-stamp. The value and error are represented as doubles
 and the time is measured in milliseconds since midnight, January 1, 1970 UTC.
 
 <p>
 Mathematic methods are provided that correctly calculate taking the error
 into account. A runtime error will occur when two measurements are used in an
 incompatible way. E.g., when a speed (m/s) is added to a distance (m). The
 measurement class will correctly track changes in unit during multiplication
 and division, always coercing the result to the most simple form. See
 <A HREF="../../../../org/osgi/util/measurement/Unit.html" title="class in org.osgi.util.measurement"><CODE>Unit</CODE></A> for more information on the supported units.
 
 <p>
 Errors in the measurement class are absolute errors. Measurement errors
 should use the P95 rule. Actual values must fall in the range value +/- error
 95% or more of the time.
 
 <p>
 A <code>Measurement</code> object is immutable in order to be easily shared.
 
 <p>
 Note: This class has a natural ordering that is inconsistent with equals. See
 <A HREF="../../../../org/osgi/util/measurement/Measurement.html#compareTo(java.lang.Object)"><CODE>compareTo(Object)</CODE></A>.
