 const epochToFullDateTime = (epochValue) => { let dateObject = new Date(epochValue); let timeStamp = dateObject.toLocaleTimeString([], { hour: "2-digit", minute: "2-digit", }); const ye = new Intl.DateTimeFormat("en", { year: "numeric" }).format(dateObject); const mo = new Intl.DateTimeFormat("en", { month: "numeric" }).format(dateObject); const da = new Intl.DateTimeFormat("en", { day: "2-digit" }).format(dateObject); let fullDateTime = `${da}/${mo}/${ye} ${timeStamp}`; return fullDateTime; }; let time = epochToFullDateTime(1598944721950); console.log(time);
