    【Question】
    What is the actual departure time of JetBlue Airways with the plane's tail number N903JB to Fort Lauderdale-Hollywood International Airport on the 20th of August 2018? actual departure time refers to DEP_TIME; JetBlue Airways refers to Description like '%JetBlue Airways%'; tail number refers to TAIL_NUM; TAIL_NUM = 'N903JB'; to refers to DEST; Fort Lauderdale-Hollywood International Airport refers to Description like '%Fort Lauderdale-Hollywood%'; on the 20th of August 2018 refers to FL_DATE = '2018/8/20';

    【Evidence】
    actual departure time refers to DEP_TIME; JetBlue Airways refers to Description like '%JetBlue Airways%'; tail number refers to TAIL_NUM; TAIL_NUM = 'N903JB'; to refers to DEST; Fort Lauderdale-Hollywood International Airport refers to Description like '%Fort Lauderdale-Hollywood%'; on the 20th of August 2018 refers to FL_DATE = '2018/8/20';

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT T1.DEP_TIME FROM Airlines AS T1 INNER JOIN `Air Carriers` AS T2 ON T1.OP_CARRIER_AIRLINE_ID = T2.Code INNER JOIN Airports AS T3 ON T1.DEST = T3.Code WHERE T1.FL_DATE = '2018/8/20' AND T1.TAIL_NUM = 'N903JB' AND T2.Description LIKE '%JetBlue Airways%' AND T3.Description LIKE '%Fort Lauderdale-Hollywood%'
