Açıklamalar

Döndürülen zaman aralığı, ayarlama kurallarının geçerli saat dilimine uygulanmasından kaynaklanan farkları içerir. Eşgüdümlü Evrensel Saat (UTC) ile saat diliminin standart saati arasındaki farkı döndüren özelliğinden BaseUtcOffset farklıdır ve bu nedenle ayarlama kurallarını dikkate almaz.

Parametrenin dateTimeKind özelliği saat dilimi nesnesine karşılık gelmiyorsa, bu yöntem bir sonuç döndürmeden önce gerekli dönüştürmeyi gerçekleştirir. Örneğin, özellik DateTimeKind.Local ancak saat dilimi nesnesi yerel saat dilimi değilse bu durum oluşabilirKind. Belirsizse dateTime veya dönüştürülen süre belirsizse, bu yöntem belirsiz saati standart saat olarak yorumlar. Geçersizse dateTime , bu yöntem UTC ile saat diliminin standart saati arasındaki farkı yansıtan bir TimeSpan nesne döndürür.

TimeZoneInfo.GetUtcOffset(DateTime) yöntemi, işlemde GetUtcOffset sınıfının yöntemine TimeZone benzer.
