The CSystemClockclass implements a system clock that provides time information and timing signals to an application. It uses the CBaseReferenceClockbase class to provide most of that functionality, adding persistence.
CSystemClockimplements the IPersistinterface. For more implementation information, see "OLE Programmers Reference (Vol. 1): Structured Storage Overview."
