时间格式转换/时间戳的转换

const d = new Date(Thu Mar 07 2019 12:00:00 GMT+0800 (中国标准时间))
const resDate = d.getFullYear() + ‘-‘ + this.p((d.getMonth() + 1)) + ‘-‘ + this.p(d.getDate())
const resTime = this.p(d.getHours()) + ‘:‘ + this.p(d.getMinutes()) + ‘:‘ + this.p(d.getSeconds())

      return s < 10 ? ‘0‘ + s : s
    },

      }
    },

        var date = new Date(timestamp * 1000);//时间戳为10位需*1000，时间戳为13位的话不需乘1000
