은은하게 코드 뿌시기

function formatDateTime(date) { var year = date.getFullYear(); var month = ('0' + (date.getMonth() + 1)).slice(-2); var day = ('0' + date.getDate()).slice(-2); var hour = ('0' + date.getHours()).slice(-2); var minute = ('0' + date.getMinutes()).slice(-2); var second = ('0' + date.getSeconds()).slice(-2); var millisecond = ('00' + date.getMilliseconds()).slice(-3); // 밀리초 return '' + year + month..
