(=> (instance ?NIGHT NightTime) (exists (?DAY1 ?DAY2) (and (instance ?DAY1 DayTime) (instance ?DAY2 DayTime) (meetsTemporally ?NIGHT ?DAY1) (meetsTemporally ?DAY2 ?NIGHT))))	Merge.kif 8343-8350	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 day time and the third time interval is an instance of day time and the time interval meets the other time interval and the third time interval meets the time interval
(=> (instance ?NIGHT NightTime) (exists (?RISE ?SET) (and (instance ?RISE Sunrise) (instance ?SET Sunset) (starts ?SET ?NIGHT) (finishes ?RISE ?NIGHT))))	Merge.kif 8352-8359	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

(=> (instance ?DAY DayTime) (exists (?NIGHT1 ?NIGHT2) (and (instance ?NIGHT1 NightTime) (instance ?NIGHT2 NightTime) (meetsTemporally ?DAY ?NIGHT1) (meetsTemporally ?NIGHT2 ?DAY))))	Merge.kif 8321-8328	If a time interval is an instance of day time, then there exist another time interval and a third time interval such that the other time interval is an instance of night time and the third time interval is an instance of night time and the time interval meets the other time interval and the third time interval meets the time interval
(=> (instance ?TIME DinnerTime) (exists (?NIGHT) (and (instance ?NIGHT NightTime) (during ?TIME ?NIGHT))))	Food.kif 230-235	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
(=> (instance ?X NightClub) (exists (?TIME) (and (standardRetailHours ?X ?TIME) (during (BeginFn ?TIME) NightTime))))	Dining.kif 394-399	If a kind of time interval is an instance of night club, then there exists an agent such that the standard retail hours for the agent are a kind of time interval and the beginning of the agent takes place during night time
