在wxml里，时间戳转换成时间

  <wxs module = "m1">
    var ToDate = function(number1){
      var n = number1 * 1000;
      var date = getDate(n);
      var Y = date.getFullYear() + '-';
      var M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1) + '-';
      var D = date.getDate() < 10 ? '0' + date.getDate() : date.getDate();
      var h = date.getHours() < 10 ? '0' + date.getHours() : date.getHours();
      var m = date.getMinutes() < 10 ? '0' + date.getMinutes() : date.getMinutes();
      return (Y + M + D + " " + h + ":" + m);
    }
    module.exports.ToDate = ToDate;
  </wxs>

  <view class='time'>{{m1.ToDate(1663257600)}}</view>
  //1663257600 --> ‘2022-09-16 00:00’
