Two Timer in One Page

I have two timers in one page but second timer is not working.

<asp:Timer ID="Timer1" runat="server" Interval="1000" OnTick="Timer1_Tick"> asp:Timer>  <asp:Timer ID="Timer2" runat="server" Interval="5000" OnTick="Timer2_Tick"> asp:Timer>

Code behind:

protected void Timer1_Tick(object sender, EventArgs e) {     lblcurrenttime5.Text = DateTime.Now.ToLongTimeString(); }         protected void Timer2_Tick(object sender, EventArgs e) {     label6.Text = "Timer 2 is working";
 }
