SystemEvents.TimeChanged fires twice

I'm using the event SystemEvents.TimeChanged in my Windows Application and it fires twice. The code that I use: ``` using System; using Microsoft.Win32; namespace DateTimeTests { class Program { static void Main(string[] args) { SystemEvents.TimeChanged += new EventHandler(SystemEvents_TimeChanged); Console.WriteLine("Press any key to exit"); Console.ReadKey(); } static void SystemEvents_TimeChanged(object sender, EventArgs e) { Console.WriteLine("Time changed: {0}", DateTime.Now); } } } ``` I tried to change the time in Windows and the event occurs twice. Why?
