本文內(nèi)容不是解決問題，而是記錄一些常用跟時間有關(guān)的方法，代碼用的是TS語言蔬墩。

第一個：傳入秒數(shù)右蒲，返回時分秒（字符串怪得，格式00:00:00）

public static TimeSecondToHMS(seconds: number): string {
    // 時
    let hour: number = Math.floor(seconds / 60 / 60);
    // 剩余秒數(shù)
    let left_second: number = seconds - hour * 60 * 60;
    // 分
    let minute: number = Math.floor(left_second / 60);
    // 秒
    let second: number = left_second - minute * 60;
    // 時間串
    let str: string = "";
    if (hour < 10) {
        str += "0";
    }
    str += hour + ":";
    if (minute < 10) {
        str += "0";
    }
    str += minute + ":";
    if (second < 10) {
        str += "0";
    }
    str += second;
    return str;
};

第二個：傳入秒數(shù)，返回分秒（字符串，格式00:00）

public static FormatTimeStr(seconds: number): string {
    let str: string = "";
    let minute: number = Math.floor(seconds / 60);
    let second: number = seconds - minute * 60;
    if (minute < 10) {
        str += "0";
    }
    str += minute + ":";
    if (second < 10) {
        str += "0";
    }
    str+= second;
    return str;
}

第三個：獲得當(dāng)前時間戳（秒級）

public static GetCurrentTimeStampSecond(): number {
    let time: number = Date.parse(new Date().toString());
    return Math.floor(time / 1000);
}

第四個：獲得本周周一零點、周日二十四點的時間戳

public static GetMondayTimeStamp(): number {
    let currentTimeStamp: number = Tools.GetCurrentTimeStampSecond();
    let currentDate: Date = new Date(currentTimeStamp * 1000);
    let dayNum: number = (currentDate.getDay() == 0) ? 7: currentDate.getDay();
    return (currentTimeStamp - (dayNum - 1) * 24 * 60 * 60 - currentDate.getHours() * 60 * 60 - currentDate.getMinutes() * 60 - currentDate.getSeconds());
}
public static GetSundayTimeStamp(): number {
    return Tools.GetMondayTimeStamp() + 7 * 24 * 60 * 60 - 1;
}
