Where do you call the initialize Timer fucntion?

VB Code:
  1. Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
  2.         Timer1.Interval = 1000
  3.         Timer1.Enabled = True
  4.  
  5.  
  6.     End Sub
  7.  
  8.     Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
  9.         Label1.Text = Now
  10.     End Sub

This is all I have in a form and it works no problem.
