Daylight saving time in .net

I am working on an ASP.NET application.

I want to know how to check if a specific date lies in the Daylight Saving Time period in Australia.

For example, I want to check 12/12/2013 12:30PM is in Daylight Saving Time in Australia or not.

NodaTime library by Jon Skeet exposes Tzdb as one of the DateTimeZoneProviders.

public void Test_NodaTime_IsDaylightSavingTime()
{
    var ts = new DateTime(1980, 4, 15, 12, 0, 0);
    var local = LocalDateTime.FromDateTime(ts);
    var zdt = Utils.TzEast.ResolveLocal(local, Utils.CustomResolver);
    Assert.IsFalse(zdt.IsDaylightSavingTime());
}

You will need to know the specific time zone you are talking about. Australia has 5 major time zones, and 13 discrete entries in the TZDB. You can read more here.

For the conversion, use TimeZoneInfo, or Noda Time.

You should also read the timezone tag wiki.

If you can be more specific, and show code for what you have tried, I will update this answer with a more detailed response.
