时间戳转年月日时分秒

  add0 (m) {
      return m < 10 ? '0' + m : m
    },
    // 时间戳转日期
    format (time) {
      // shijianchuo是整数，否则要parseInt转换
      var time1 = new Date(time)
      var year = time1.getFullYear()
      var month = time1.getMonth() + 1
      var day = time1.getDate()
      let h = time1.getHours() >= 10 ? time1.getHours() : '0' + time1.getHours()
      let m = time1.getMinutes() >= 10 ? time1.getMinutes() : '0' + time1.getMinutes()
      // let s = time1.getSeconds() >= 10 ? time1.getSeconds() : '0' + time1.getSeconds()
      return year + '-' + this.add0(month) + '-' + this.add0(day) + ' ' + h + ':' + m
    }
