Clock on webpage using server and system time?

Question

I need to add a clock to a web page. The clock needs to be synchronized with a server but I really don\'t want to have it constantly check the server as the page will be ope

Answer 1

you just get one time date time from server, on load call this method and use moments js for format date:

var timeMiliSecond = new Date(serverTime).getTime();
 callRepeatedly() {
    setTimeout(() => {
         timeMiliSecond = timeMiliSecond+1000;         
         serverTime=moment(newDate(timeMiliSecond)).format('MM-DD-YYYY HH:mm:ss');
         this.callRepeatedly();
      }, 1000)  
  }
