(=> (instance ?NIGHT NightTime) (exists (?RISE ?SET) (and (instance ?RISE Sunrise) (instance ?SET Sunset) (starts ?SET ?NIGHT) (finishes ?RISE ?NIGHT))))	Merge.kif 8999-9006	If a time interval is an instance of night time, then there exist another time interval and a third time interval such that the other time interval is an instance of sunrise and the third time interval is an instance of sunset and the third time interval starts the time interval and the other time interval finishes the time interval

consequent

(=> (and (instance ?X NightClub) (standardRetailHours ?TIME ?X)) (exists (?T) (and (instance ?T ?TIME) (during ?T NightTime))))	Dining.kif 419-426	If an agent is an instance of night club and the standard retail hours for the agent are a kind of time interval, then there exists another time interval such that the other time interval is an instance of a kind of time interval and the other time interval takes place during night time

(=> (instance ?TIME DinnerTime) (exists (?NIGHT) (and (instance ?NIGHT NightTime) (during ?TIME ?NIGHT))))	Food.kif 1890-1895	If a time interval is an instance of dinner time, then there exists another time interval such that the other time interval is an instance of night time and the time interval takes place during the other time interval
