1.获取时间戳(秒)
new Date().getTime()/1000 Date.now()/1000
2.日期时间格式化
const formatNumber = (n: number) => { const s = n.toString() return s[1] ? s : '0' + s } const formatTime = (date: Date) => { const year = date.getFullYear() const month = date.getMonth() + 1 const day = date.getDate() const hour = date.getHours() const minute = date.getMinutes() const second = date.getSeconds() return ( [year, month, day].map(formatNumber).join('-') + ' ' + [hour, minute, second].map(formatNumber).join(':') ) } let d=formatTime(new Date()) console.log(d) //2022-01-04 11:11:08
