2026年底将不会引入闰秒 -- No leap second will be introduced at the end of December 2026

文章摘要

IERS公告C72显示,2026年12月底不会引入闰秒,目前协调世界时(UTC)与国际原子时(TAI)的差值为-37秒,该状态自2017年1月1日起保持至今。

文章总结

国际地球自转与参考系统服务(IERS)于2026年7月6日发布第72号公告C,通知时间测量与分发机构:2026年12月底将不会引入闰秒。自2017年1月1日0时起,协调世界时(UTC)与国际原子时(TAI)的差值保持为UTC-TAI = -37秒。闰秒可在每年6月或12月底根据UT1-TAI的变化引入,该公告每六个月发布一次,以宣布UTC的时间调整或确认下一次可能调整日期无变化。

评论总结

根据评论内容,主要观点和论据如下:

1. 对取消闰秒的确认与讨论 - 评论1(Wingy)询问:“这是否意味着负闰秒不再发生?”("Does this mean the negative leap second isn't happening anymore?") - 评论15(ComputerGuru)指出:“这个公告没什么实质内容;基本上已经决定不再添加闰秒了(在我们有生之年)。”("This announcement is very much a nothing burger; it's already been more or less decided that adding leap seconds just isn't going to be a thing anymore.")

2. 技术影响与抽象层问题 - 评论4(srean)关注:“像Spanner这样的系统在这种情况下会怎样?是头疼问题还是无关紧要?”("What happens to systems such as Spanner under these circumstances? Is it a headache or a non-issue?") - 评论7(returningfory2)提出:“闰秒一直存在于错误的抽象层。它们应该与闰日和夏令时一样,存在于时区层。”("I feel leap seconds have always lived in the wrong abstraction layer. They should live in the same abstraction layer that does leap days and daylight savings: the time zones.")

3. 对时间维护工作的调侃与致敬 - 评论8(t1234s)建议:“应该设立一个全球假日,来庆祝那些维护操作系统内核中时间/日期相关代码、防止世界崩溃的人。”("They should have a global holiday to celebrate the people who maintain time/date related code in OS kernels that keeps the world from imploding.") - 评论6(delichon)幽默提议:“我们可以沿赤道安装喷气发动机,旋转180度来获得或失去时间,然后连接到我的贪睡按钮。”("We can just mount jet engines along the equator and rotate them 180 to gain or lose time. And then connect them to my snooze button.")

4. 对时间偏移的疑问与澄清 - 评论9(exegete)困惑:“原子钟比太阳钟慢37秒?我也不理解2017年的引用。”("This means the atomic clock is behind the solar clock by 37 seconds? I also don't understand the reference to 2017.") - 评论12(KboPAacDA3)解释:“如果UTC-TAI偏移保持-37秒,那么UTC-GPS偏移也保持-18秒。TAI和GPS之间有恒定的19秒偏移。”("If the UTC-TAI offset remains at -37s, then it also means the UTC-GPS offset remains at -18s. TAI and GPS have a constant 19s offset from each system.")

5. 对地球自转不可预测性的好奇 - 评论10(doctoboggan)提问:“是什么导致了这种不可预测性?我原以为我们对地球自转和轨道的了解已经精确到很多小数位。是地质活动、天气还是其他原因导致自转速度变化而无法预测?”("What causes the unpredictability in this? I would have guessed we have earth's rotation and orbit down to many decimals. Does geological activity, weather, or something else cause rotation speed differences that we just can't predict?")

6. 其他轻松评论 - 评论14(clircle):“太好了,今年12月我不需要调慢时钟了。”("Cool, I don't have to set my clocks back this December.") - 评论16(Surac):“世界将在12月26日结束,所以不需要闰秒。”("World will end at 26 December so no leap second needed.")
