We are going to convert epoch timestamp into a date-time string. function convertDateTime(timeStamp){     var milliSecTimeStamp = 0;     if(String(timeStamp).length <= 10){         milliSecTimeStamp = parseInt(timeStamp)*1000;     }else{         milliSecTimeStamp = parseInt(timeStamp);     }     var dateTime = new Date(milliSecTimeStamp);     var date = dateTime.getDate();     var month = dateTime.getMonth();     var year = dateTime.getFullYear();     var dateFormat = date+'-'+month+'-'+year;     return dateFormat; }
