WHAT are the primary tests (in the sense described on p. 71) for temporal interval? To say that an event occurred n units of time after another event is to say that if a true clock recorded a certain reading at the place of the first event at the instant of its occurrence, then a true clock previously synchronised with the former would record a reading greater by n units at the place of the second event at the instant of its occurrence. Statements about temporal interval are statements about what would have been or would be the behaviour of true clocks.
