A Temporal Connection
refers to a trigger span, such as "before" or "during", which signifies that two or more Events occurred within a chronological sequence. The types of Temporal Connections
are:
- before
- during

- encounter
Note that encounter refers to two events that take place in the same Encounter, though not necessarily simultaneously.
A phrase such as before, after, or during, or of (if, for example, preceded by 'within 3 days of....).
