Just to add up, here's a function to return a timestamp string in Javascript. Example: 15:06:38 PM

function displayTime() {
    var str = "";

    var currentTime = new Date()
    var hours = currentTime.getHours()
    var minutes = currentTime.getMinutes()
    var seconds = currentTime.getSeconds()

    if (minutes < 10) {
        minutes = "0" + minutes
    }
    if (seconds < 10) {
        seconds = "0" + seconds
    }
    str += hours + ":" + minutes + ":" + seconds + " ";
    if(hours > 11){
        str += "PM"
    } else {
        str += "AM"
    }
    return str;
}
