datetime 형식을 서버스크립트로 값을 받아보면

2010-7-12 오후 7:30:00

과 같이 골때리게 나올 경우 24시간제로 어떻게 해야할까?



# 가장 우선되는 해결책은

시스템 날짜 포맷을 바꿔주는 것이다.

시작 > 제어판 > 국가 및 언어 옵션 > [사용자 지정] > 시간 탭

시간 형식 : HH:mm:ss

오전 형식 : AM

오후 형식 : PM

로 선택 또는 수정 후 [확인].

재부팅 없이 바로 적용된다.



# 시스템 날짜 포맷을 바꿀 수 없을때는

서버 스크립트로 별짓을 다 해보아도 소용 없으니

Select 쿼리를 줄때 해결하는게 제일 좋다.

SELECT convert(VARCHAR, '2016-10-23 20:44:11', 120)

와 같이 반환받으면 yyyy-mm-dd hh:mm:ss(24h) 로 반환된다.


아래는 갖가지 날짜형식 변한하여 받는 레퍼런스이다.
