时间戳转具体日时分秒

用于需要查询具体时间段的函数，传入时间戳 返回具体时分秒

function transformTime(timestamp) { 
  const DAY_MILLISECOND = 86400000;
  const HOUR_MILLISECOND = 3600000;
  const MINUTE_MILLISECOND = 60000;

  const dayValue = (timestamp / DAY_MILLISECOND) | 0;
  const hourValue = ((timestamp % DAY_MILLISECOND) / HOUR_MILLISECOND) | 0;
  const minValue =
    (((timestamp % DAY_MILLISECOND) % HOUR_MILLISECOND) / MINUTE_MILLISECOND) |
    0;
  const secondValue =
    ((((timestamp % DAY_MILLISECOND) % HOUR_MILLISECOND) % MINUTE_MILLISECOND) /
      1000) |
    0;

  const day = dayValue ? dayValue.toString().padStart(2, "0") + "天" : "";
  const hour =
    day || hourValue ? hourValue.toString().padStart(2, "0") + "时" : "";
  const minute =
    hour || minValue ? minValue.toString().padStart(2, "0") + "分" : "";
  const second =
    minute || secondValue ? secondValue.toString().padStart(2, "0") + "秒" : "";

  return day + hour + minute + second;
}
