//
//  Purpose: declares the WBEMTime and WBEMTimeSpan objects which are 
//  similar to the MFC CTime and CTimeSpan objects.  The WBEM versions
//  are capable of storing down to the nsec and also have functions for
//  Creating from and getting BSTRs.
//
//  Note; The current implementation of WBEMTime does not support dates 
//  before 1601;
