The custom date function works funky sometime

Question

I'm using the below script to custom my date, sometimes when the time is less than minute it works funky like that.

How can i custom it to say 1 min ago if the date is less than a minute? or simply remove the seconds ago functionality?

-9236 seconds ago

function dateFormatter(date) {

    var seconds = Math.floor((new Date() - date) / 1000);

    var interval = Math.floor(seconds / 31536000);

    if (interval > 1) {
        return interval + " Years Ago ";
    }
    interval = Math.floor(seconds / 2592000);
    if (interval > 1) {
        return interval + " Months Ago ";
    }
    interval = Math.floor(seconds / 86400);
    if (interval > 1) {
        return interval + " Days Ago ";
    }
    interval = Math.floor(seconds / 3600);
    if (interval > 1) {
        return interval + " Hrs ago ";
    }
    interval = Math.floor(seconds / 60);
    if (interval > 1) {
        return interval + " mins ago ";
    }
    return Math.floor(seconds) + " seconds ago";
}
