How can I use call with setInterval to get an object literal to invoke one of its own methods?

Here's an example.
This works, and I understand why it works.
The timer object calls its own tick method once each second

var timer =

{ 

  start: function()

  {

    var self = this;

    setInterval(function(){self.tick();}, 1000);



  },



  tick: function()

  {

    console.log(tick!);

  }

};



timer.start();

I tried to simplify this code by using call.
This next example is the best that I came up with.
But it doesn't work: the tick method is called only once, and then I get a type error.

var timer =

{ 

  start: function()

  {

    setTimeout.call(this, this.tick(), 1000);

  },



  tick: function()

  {

    console.log(tick!);

  }

};



timer.start();

I think I don't really understand how call works.
Can anyone explain what I'm doing wrong?
