countdown true seconds 0 makes clock

[darthjysky]

    $('#countDownDiv').timeTo({
        seconds: 0,
        displayCaptions: true,
        fontSize: 30,
        countdown: true,
        captionSize: 14,
        countdownAlertLimit: 0,
        start: false,
        callback: timeIsUp
    });

makes clock instead of countdown with zeros. countdown: true, does not seem to have any affect here.
