时间字符串&时间戳转换

// 获取当前时间
var time = Date.parse(new Date()) / 1000;

// 时间字符串转时间戳的两种方法
var time = ‘2020 - 06 - 30 00: 00: 00’；
1. time = new Date(Date.parse(time.replace(/-/g, "/"))).getTime() / 1000;
2. time = new Date(time).getTime() / 1000；

// 时间戳转时间字符串
var time = ‘1566012105‘
let stampLength = time.toString().length
let tstamp
if (stampLength == 10) {
    tstamp = new Date(stamp * 1000)
} else if (stampLength == 13) {
    tstamp = new Date(stamp)
} else if (stampLength == 19) {
    tstamp = new Date(stamp)
} else {
    console.warn(‘GetFormatTime warn: 请传入正确的时间戳‘)
    return
}

let year = tstamp.getFullYear(tstamp)
let month = tstamp.getMonth(tstamp) + 1
let day = tstamp.getDate(tstamp)
let hour = tstamp.getHours(tstamp)
let minute = tstamp.getMinutes(tstamp)
let second = tstamp.getSeconds(tstamp)
if (month < 10) {
    month = ‘0‘ + month
}
if (day < 10) {
    day = ‘0‘ + day
}
