In case if you are getting time like this "16:26", "12:50", "05:23", etc. Then, you can easily convert them into 12 hour format like "4:26 PM", "12:50 PM", "05:23 AM", etc. with AM/PM through this function.

function convertTo12Hour(oldFormatTime) {
    console.log("oldFormatTime: " + oldFormatTime);
    var oldFormatTimeArray = oldFormatTime.split(":");

    var HH = parseInt(oldFormatTimeArray[0]);
    var min = oldFormatTimeArray[1];

    var AMPM = HH >= 12 ? "PM" : "AM";
    var hours;
    if(HH == 0){
      hours = HH + 12;
    } else if (HH > 12) {
      hours = HH - 12;
    } else {
      hours = HH;
    }
    var newFormatTime = hours + ":" + min + " " + AMPM;
    console.log(newFormatTime);
}
