/*
* REVISIONS:
*  pcy30Nov92: Changed obj.h to apcobj.h; InsertEventTimer now returns VOID.
*  jod07Dec92: Added a pure virtual Wait function to TimerManager.
*  pcy11Dec92: Added global _theTimerManager
*  ane11Dec92: Moved mainapp.h
*  ane16Dec92: Added default constructors for date/time classes
*  ane22Dec92: Added constructor to take string of form "8:00 AM"
*  ane11Jan93: Changed theTimerList to a sortable list
*  ane08Feb93: Added new RemoveEventTimer function
*  ajr22Feb93: Changed case of mainApp.h to mainapp.h
*  jod05Apr93: Added changes for Deep Discharge
*  cad09Jul93: allowing access to findeventtimer
*  cad16Sep93: Added -, < operators to DateObj, made some methods const
*  cad28Sep93: Made sure destructor(s) virtual
*  cad12Oct93: Added == operator
*  ajr02May95: Need to stop carrying time in milliseconds
*  tjg26Jan98: Added Stop method
*  mholly03Dec98    : removed theAccessLock and instead use the Access/Release
*                   methods already available in theTimerList.  Also removed
*                   the Suspend()/Release()/IsSuspended() methods (not used)
