이러한 지침에서는 샘플 버스 출발 데이터를 사용합니다. 여기서 24시간 타임스탬프는 숫자 필드에 저장됩니다(예: 오전 8시 35분은 835). 24시간 타임스탬프가 이미 앞에 0이 있는 문자열 필드(일명 텍스트 유형)인 경우 다음 단계가 모두 필요하지 않을 수 있습니다.
DATEPARSE("hmm",[Scheduled Departure Time])
//if the data contains a leading zero then use "hhmm" instead of "hmm"
DATETIME( "1/1/1900 " //arbitrary date + IF LEN([Scheduled Departure Time]) = 3 THEN "0" ELSE "" END //add a leading zero if the timestamp is only 3 characters long + [Scheduled Departure Time] )
