使用js将Unix时间戳转换为普通时间

var unixtime=1358932051;
formatTime (time) {
        let unixtime = time
        let unixTimestamp = new Date(unixtime * 1000)
        let Y = unixTimestamp.getFullYear()
        let M = ((unixTimestamp.getMonth() + 1) > 10 ? (unixTimestamp.getMonth() + 1) : '0' + (unixTimestamp.getMonth() + 1))
        let D = (unixTimestamp.getDate() > 10 ? unixTimestamp.getDate() : '0' + unixTimestamp.getDate())
        let toDay = Y + '-' + M + '-' + D
        return toDay
      }
