Check if a date and time(DateTimeOffset) is daylight saving time for time zone from TimeZoneInfo in CSharp
Description
The following code shows how to check if a date and time(DateTimeOffset) is daylight saving time for time zone from TimeZoneInfo.
Example
//from w w w . j a v a 2s . c om
using System;
public class MainClass
{
public static void Main(String[] argv)
{
DateTimeOffset unclearDate = DateTimeOffset.Now;
Console.WriteLine("In the {0}, {1} is {2}ambiguous.",
TimeZoneInfo.Local.DisplayName,
unclearDate,
TimeZoneInfo.Local.IsAmbiguousTime(unclearDate) ? "" : "not ");
// Test if time is DST.
Console.WriteLine("In the {0}, {1} is {2}daylight saving time.",
TimeZoneInfo.Local.DisplayName,
unclearDate,
TimeZoneInfo.Local.IsDaylightSavingTime(unclearDate) ? "" : "not ");
if (TimeZoneInfo.Local.IsAmbiguousTime(unclearDate) ||
TimeZoneInfo.Local.IsDaylightSavingTime(unclearDate))
Console.WriteLine("{0} may be daylight saving time in {1}.",
unclearDate, TimeZoneInfo.Local.DisplayName);
}
}
The code above generates the following result.
