The GetDaylightChanges method returns specific daylight saving information for a given year:

 
using System;
using System.Globalization;
public class MainClass {
    public static void Main() {
        TimeZone zone = TimeZone.CurrentTimeZone;
        DaylightTime day = zone.GetDaylightChanges(2008);
        Console.WriteLine(day.Start);
        Console.WriteLine(day.End);
        Console.WriteLine(day.Delta);
    }
}

The IsDaylightSavingTime and GetUtcOffset methods work as follows:

 
using System;
public class MainClass {
    public static void Main() {
        TimeZone zone = TimeZone.CurrentTimeZone;
        DateTime dt1 = new DateTime(2008, 1, 1);
        DateTime dt2 = new DateTime(2008, 6, 1);
        Console.WriteLine(zone.IsDaylightSavingTime(dt1));
        Console.WriteLine(zone.IsDaylightSavingTime(dt2));
        Console.WriteLine(zone.GetUtcOffset(dt1));
        Console.WriteLine(zone.GetUtcOffset(dt2));
    }
}

The static TimeZone.CurrentTimeZone method returns a TimeZone object based on the current local settings

 

using System;
public class MainClass {
    public static void Main() {
        TimeZone zone = TimeZone.CurrentTimeZone;
        Console.WriteLine(zone.StandardName);
        Console.WriteLine(zone.DaylightName);
    }
}
