    time.gmtime([secs])	time.localtime([secs])
        secs にはエポック(上記を参照)からの秒数で表される時間をします。
        この指定の時間を８項目のタプル
        (year, month, mday, hour, minute, second, weekday, yearday)
        に変換します。
        secs を与えないか None である場合は RTC の現在時間を使います。
        ８項目のタプルのフォーマットは次のとおりです:
        year:	 西暦の年(たとえば 2025)
        month:	 月を表す 1-12
        mday:	 日を表す 1-31
        hour:	 時を表す 0-23
        minute:	 分を表す 0-59
        second:	 秒を表す 0-59
        weekday: 月曜-日曜を表す 0-6
        yearday: 年内の通算日数を表す 1-366
