Problem with DateTime matching.

I'm trying to match a certain DateTime value with the current system DateTime. I have a timer and a label on a form. Timer interval is set to 1000. When the form loads, the timer starts ticking. As soon as the current DateTime matches the value of the variable, it shows a message in the label.

When I'm writing the following code, the values don't match even if the current system DateTime is equal to the variable. Label1 isn't showing 'Times Matched':

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        Dim dtmNow As DateTime
        dim dtmVar as DateTime=#04/28/2010 03:25:00 AM#
        
            dtmNow = Now
            If dtmVar = dtmNow Then Label1.Text = "Times Matched"
    End Sub

But when I'm writing the same code by parsing 'Now' into DateTime it's working fine.

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        Dim dtmNow As DateTime
        dim dtmVar as DateTime=#04/28/2010 03:25:00 AM#
        
            dtmNow = DateTime.Parse(Now.ToString)
            If dtmVar = dtmNow Then Label1.Text = "Times Matched"
    End Sub

Why is it so? The default format of 'Now' is the same as I have stored in dtmVar variable. So there's no question of format mismatch. Does that mean 'Now' is not actually a DateTime property?
Provided, my O.S. is Windows Vista Ultimate and all date/time settings are set to default.
