Exempel

I följande exempel skapas tidszonsövergångar för en imaginär tidszon med hjälp av både en regel för fast datum och en regel för flytande datum. Regeln för fast datum definierar en tidszonsjustering som börjar kl. 02:00 den 15 mars och slutar kl. 03:00 den 15 november för åren 1900 till 1955.

Kommentarer

Den här metoden skapar en fast datumregel (d.s. en tidsändring som inträffar en viss dag i en viss månad). Till exempel följer en tidsändring som alltid inträffar den 28 oktober en fast datumregel.

För övergångar från standardtid till sommartid timeOfDay representerar argumentet tiden för övergången i tidszonens standardtid. För övergångar från sommartid till standardtid representerar den tiden för övergången i tidszonens sommartid. Observera att det här är ett DateTime värde vars värden för år, månad och datum måste vara lika med 1.
