ISO标准时间

方法1

var m = new Date("2019/06/05 00:00:00").getTime()
var n = new Date("2019/06/10 00:00:00").getTime()
var time0 = new Date(Math.floor(Math.random() * (n - m)) + m).toISOString()
var x = new Date(time0).getTime()
var time1 = new Date(Math.floor(Math.random() * (n - x)) + x).toISOString()

方法2

var date0 = new Date(util.formatTime(new Date(Math.floor(Math.random() * (n - m)) + m)))
var datestamp0 = date0.getTime() / 1000
var date1 = new Date(util.formatTime(new Date(Math.floor(Math.random() * (n - datestamp0 * 1000)) + datestamp0 * 1000)))
var datestamp1 = date1.getTime() / 1000
var time0 = util.formatUTCTime(datestamp0, 'Y-M-DTh:m:s.165Z')
var time1 = util.formatUTCTime(datestamp1, 'Y-M-DTh:m:s.165Z')

const formatTime = 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(':')
}

function formatUTCTime(number, format) {
  var formateArr = ['Y', 'M', 'D', 'h', 'm', 's'];
  var returnArr = [];
  var date = new Date(number * 1000);
  returnArr.push(date.getFullYear());
  returnArr.push(formatNumber(date.getMonth() + 1));
  returnArr.push(formatNumber(date.getDate()));

  returnArr.push(formatNumber(date.getHours()));
  returnArr.push(formatNumber(date.getMinutes()));
  returnArr.push(formatNumber(date.getSeconds()));
  for (var i in returnArr) {
    format = format.replace(formateArr[i], returnArr[i]);
  }
  return format;
}

方法3

let d = new Date();
let month = (d.getMonth() + 1) < 10 ? '0' + (d.getMonth() + 1) : (d.getMonth() + 1);
let day = d.getDate() < 10 ? '0' + d.getDate() : d.getDate();
let hours = d.getHours() < 10 ? '0' + d.getHours() : d.getHours();
let min = d.getMinutes() < 10 ? '0' + d.getMinutes() : d.getMinutes();
let sec = d.getSeconds() < 10 ? '0' + d.getSeconds() : d.getSeconds();

let times = d.getFullYear() + '-' + month + '-' + day + ' ' + hours + ':' + min + ':' + sec;
