How to create a Timer that does something?

Question

I'm quite new in XNA C# and I would like to know how do I create a timer in XNA C# that does something after few seconds.

I've seen a Flash tutorial that does what I need but I don't know how to do it in XNA C#

I'm trying to use a timer to make a blinking model in certain period of my project. Therefore, I need to know how do I start the timer and how does the timer toggle the blinking of my model.

Thanks.

Do something like below in update

float elapsedTime = (float)gameTime.ElapsedGameTime.TotalSeconds;

then have a variable for seconds like

float timer = 5.0f; // Five seconds

then in update

timer -= elapsedTime

if(timer <= 0)
{
    // Hanlde the blink here
    timer = 5.0f; // Reset timer
}
