Because Timers are a scarce system resource, I would handle it by having a Clock class (or UserControl) which held a static Timer instance. Each individual Clock instance would hook an event handler to the static Timer, so the minimum system resources would be used:
C#
public partial class Clock : UseControl
    {
    private static Timer tim = new Timer();
    public static Clock()
        {
        tim.Tick = 1000;   // One second intervals
        tim.Start();
        }
    public Clock()
        {
        InitializeComponent();
        tim.Tick += new EventHandler(tim_Tick);
        }

    void tim_Tick(object sender, EventArgs e)
        {
        Console.WriteLine(DateTime.Now);
        }
    }
