My C# code is as follows: CollapseCopy Code
System.Timers.Timer timer = new System.Timers.Timer(1000);
public Window1()
{
    InitializeComponent();    MDCalendar mdCalendar = new MDCalendar();
    DateTime date = DateTime.Now;
    TimeZone time = TimeZone.CurrentTimeZone;
    TimeSpan difference = time.GetUtcOffset(date);
    uint currentTime = mdCalendar.Time() + (uint)difference.TotalSeconds;
    persianCalendar.Content = mdCalendar.Date("Y/m/D  W", currentTime, true);
    christianityCalendar.Content = mdCalendar.Date("P Z/e/d", currentTime, false);    timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);
    timer.Enabled = true;
}void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
    this.Dispatcher.Invoke(DispatcherPriority.Normal, (Action)(() =>
    {
        secondHand.Angle = DateTime.Now.Second * 6;
        minuteHand.Angle = DateTime.Now.Minute * 6;
        hourHand.Angle = (DateTime.Now.Hour * 30) + (DateTime.Now.Minute * 0.5);
    }));
}private void Grid_MouseDown(object sender, MouseButtonEventArgs e)
{
    this.DragMove();
}
