설명

표준 시간에서 일광 절약 시간으로 전환하는 경우 값은 TimeOfDay 표준 시간대의 표준 시간의 전환 시간을 나타냅니다. 일광 절약 시간에서 표준 시간으로 전환하는 경우 표준 시간대의 일광 절약 시간제 전환 시간을 나타냅니다.

속성은 TimeOfDay 시간 변경 시간만 정의하지만 날짜는 정의하지 않습니다. 날짜는 고정 규칙 변경에 Month 대한 및 Day 속성과 부동 규칙 변경에 Month대한 , Week및 DayOfWeek 속성에 의해 결정됩니다. 이 DateTime 값의 날짜 구성 요소는 무시됩니다. 연도, 월 및 일의 값은 항상 1입니다.

속성은 TimeOfDay 고정 날짜 및 부동 날짜 전환 모두에 사용됩니다.
