You will not see the timer component inside the form because it has not a visual rapresentation, it will be added under the component bar, below the graphic form.

Enabled: True
Interval: 1000 (millisecons), so it refresh every 1 second

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            label1.Text = DateTime.Now.Second.ToString(); // it renders: 15 16 17 18 etc...
        }
    }
}
