/*
*   The timers is an object that stores an alarm
*   setting, and an action to be performed when the alarm
*   setting is reached. This is an abstract object.
*
* REVISIONS:
*  pcy02Dec92: Removed include of typedefs.h 
*  jod07Dec92: Added new Sorted List to the object.
*  pcy14Dec92: Changed Sortable to ApcSortable 
*  ane11Jan93: Added copy constructor
*  ane18Jan93: Implemented Equal operator
*  pcy16Jan93: Timers are now in seconds since time in msec is too big
