How to count time?

I explain, i'm working on a game that give you points if you choose the correct answer to a question. Now the points are always the same but i want to give points depending of how fast is the user answering. Any idea of "counting time" and transforming into points (my english is so bad... sorry)

    Sure -- you can use ECMAScript's built-in Date object to do that.

    When you ask a question, remember the time you did it:

    // startTime must not be a local variable; it needs to persist
    startTime = new Date();

    Then when you get the answer from the user, get the current time:

    var now = new Date();

    Then get the difference, in seconds:

    var diffInSeconds = (now.valueOf() - startTime.valueOf()) / 1000
