Just set your desire country timezone and You can easily show in html it update using SetInteval() function after every one minut. function formatAMPM() manage 12 hour format and AM/PM time display.

$(document).ready(function(){
        var pakTime = new Date().toLocaleString("en-US", {timeZone: "Asia/Karachi"});
        pakTime = new Date(pakTime);

        var libyaTime = new Date().toLocaleString("en-US", {timeZone: "Africa/Tripoli"});
        libyaTime = new Date(libyaTime);



         document.getElementById("pak").innerHTML = "PAK  "+formatAMPM(pakTime);
         document.getElementById("ly").innerHTML = "LY   " +formatAMPM(libyaTime);

        setInterval(function(today) {
            var pakTime = new Date().toLocaleString("en-US", {timeZone: "Asia/Karachi"});
            pakTime = new Date(pakTime);

            var libyaTime = new Date().toLocaleString("en-US", {timeZone: "Africa/Tripoli"});
            libyaTime = new Date(libyaTime);


           document.getElementById("pak").innerHTML = "PAK  "+formatAMPM(pakTime);
           document.getElementById("ly").innerHTML = "LY  " +formatAMPM(libyaTime);

        },10000);

         function formatAMPM(date) {
            var hours = date.getHours();
            var minutes = date.getMinutes();
            var ampm = hours >= 12 ? 'pm' : 'am';
            hours = hours % 12;
            hours = hours ? hours : 12; // the hour '0' should be '12'
            minutes = minutes < 10 ? '0'+minutes : minutes;
            var strTime = hours + ':' + minutes + ' ' + ampm;
            return strTime;
        }


    });
