    {
        Timer timer = new Timer(200);
        timer.Elapsed += Timer_Elapsed;
        timer.Start();
        while (true)
        {
            // Infinite loop.
        }
    }
    
    private static void Timer_Elapsed(object sender, ElapsedEventArgs e)
    {
        // Use SignalTime.
        DateTime time = e.SignalTime;
        Console.WriteLine("TIME: " + time);
    }

The result is this:
