// Description:
//      Class BdbDuration.  
//      This is a time duration class.  
//      Note that a time duration is positive definite, thus 
//      d = abs( d1 - d2 ), 
//      and
//      d = abs( t1 - t2 ).
//
// Environment:
//      Software developed for the BaBar Detector at the SLAC B-Factory.
