Příklady

Následující příklad vypíše časová pásma zjištěná v místním počítači a zobrazí informace o době přechodu pro všechny přechody s plovoucím datem.The following example enumerates the time zones found on the local computer and displays transition time information for all floating-date transitions. Časové informace zahrnují den v týdnu, kdy se změna projeví.The time information includes the day of the week on which the time change occurs.

Poznámky

Vlastnost vrací platnou hodnotu pouze v případě, IsFixedDateRule že vlastnost je false. DayOfWeekThe DayOfWeek property returns a valid value only if the IsFixedDateRule property is false.

DayOfWeek Vlastnost označuje den v týdnu, ve kterém je použito pravidlo s plovoucím datem (například Druhá neděle v listopadu).The DayOfWeek property indicates the day of the week on which a floating-date rule is applied (for example, the second Sunday of November). Naproti tomu Day vlastnost označuje den v měsíci, kdy se použije pravidlo s pevným datem (například 15. dubna).In contrast, the Day property indicates the day of the month on which a fixed-date rule is applied (for example, April 15).
