Tips:时间戳和时间（YY-MM-DD Hh:mm:ss）的相互转换

时间戳转换为时间:

function timestampToTime(timestamp) {
    timestamp = Number(timestamp ? timestamp : null)
    let date = new Date(timestamp)// 时间戳为10位需*1000，时间戳为13位的话不需乘1000
    let Y = date.getFullYear()
    let M = date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1
    let D = date.getDate() < 10 ? '0' + date.getDate() : date.getDate()
    let h = date.getHours() < 10 ? '0' + date.getHours() : date.getHours()
    let m = date.getMinutes() < 10 ? '0' + date.getMinutes() : date.getMinutes() 
    let s = date.getSeconds() < 10 ? '0' + date.getSeconds() : date.getSeconds()
    return `${Y}/${M}/${D} ${h}:${m}:${s}`
}

时间转换为时间戳:

function timeToTimestamp(time) {
    let timestamp = new Date(time).getTime()
    return timestamp
}
