How Is This Method Working?!

[Fanatic2012]

I am using the compare() method to check a saved date and time in a variable by the user VS the system's current time, "Now". The compare() method return -1 if the first date and time is less than the current time, or 0 if the saved date and time is equal to the current time. How is it working (making the application visible when the times are equal) if it's returning -1 from what I can see in the code.

private void timer1_Tick(object sender, EventArgs e)
{
if (remindTime.CompareTo(DateTime.Now) < 0) //when the dates are equal it should return 0 so this.Visible = true; will not run, but it does.
{
this.Visible = true;
}
}


Thank you all in advance!
