Each of the constituent elements of the downhole component object (e.g., each item of equipment in a string) has a date element called event info. This event info element represents either the beginning or ending event for the item, and it contains a timestamp and a pointer reference to the well CM ledger entry corresponding to this event (thereby providing the link referred to above between event and equipment).
