NSTimeInterval: A Explanation of Time Stamps"

下面是重构后的代码：

```typescript

function timestampToMinutes(timeStamp: number): string {

// 时间戳 --> 分钟

var timeInterval = (60 * 60 * 24) + (60 * 60 * 5) + (60 * 3) + (20);

var dateStr = "";

if (timeInterval >= 60 * 60 * 24) {

let v = timeInterval / (60 * 60 * 24);

timeInterval -= (60 * 60 * 24) * v;

dateStr += `${v}天`;

}

if (timeInterval >= 60 * 60) {

let v = timeInterval / (60 * 60);

timeInterval -= (60 * 60) * v;

dateStr += `${v}小时`;

}

if (timeInterval >= 60) {

let v = timeInterval / (60);

timeInterval -= (60) * v;

dateStr += `${v}分`;

}

dateStr += `${timeInterval}秒`;

return dateStr;

}

// Example usage:

console.log(timestampToMinutes(1728931202)); // Output: "2天5小时3分20秒"

```
