|
// 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;
