Açıklamalar

İki TimeZoneInfo.AdjustmentRule nesnenin Equals(TimeZoneInfo+AdjustmentRule) eşit olup olmadığını belirlemek için yöntemi her nesnenin üye değerlerini karşılaştırır. İki ayarlama kuralı, ve özellikleri tarafından DaylightTransitionStartDaylightTransitionEnd döndürülen nesneler için aynı geçerlilik tarihlerine, aynı deltaya ve aynı değerlere TimeZoneInfo.TransitionTime sahipse eşittir.
