[removed] convert 24-hour time-of-day string to 12-hour time with AM/PM and no timezone

Question

The server is sending a string in this format: 18:00:00. This is a time-of-day value independent of any date. How to convert it to 6:00PM in Javasc

Assuming you will get the date string in a proper format, I have a solution.

function parseDateTime(dt) {
        var date = false;
        if (dt) {
            var c_date = new Date(dt);
            var hrs = c_date.getHours();
            var min = c_date.getMinutes();
            if (isNaN(hrs) || isNaN(min) || c_date === "Invalid Date") {
                return null;
            }
            var type = (hrs <= 12) ? " AM" : " PM";
            date = ((+hrs % 12) || hrs) + ":" + min + type;
        }
        return date;
    }

    parseDateTime("2016-11-21 12:39:08");//"12:39 AM"
    parseDateTime("2017-11-21 23:39:08");//"11:39 PM"
