Google: allows any organization to use NTP servers to cope with the end of 2016 leap seconds-IT information

Beijing time on December 1, according to foreign media reports, Google will allow any organization to use NTP (network time protocol) server, the leap seconds would help IT organizations cope with the end of 2016.

Leap seconds are set up to keep civil time in line with the rotation of the Earth, for the average person has little effect, but rely on close synchronization of different systems applications and services will have a serious impact.

Most Internet terminals available through NTP time service. Google team Technical Director of maikeer·xierzi (Michael Shields) on Wednesday published a blog post saying that Google has its own NTP server, systems that use them to help you deal with leap seconds.

Common operating systems can't handle leap seconds, so some organizations developed a special method, but sometimes these specialized method itself can cause problems. Google, a representative said, the last part of Google's system there have been strikes in the event of a leap second, although did not have an impact on its service.

To do this, Google will revise its NTP server, the leap seconds before and after the 10-hour clock frequencies within a period of 0.0014%. Since the leap second since 2008, Google has been using this technology.

Google isn't the only company using this technology. Akamai plans to slow down system in transition period of 24 hours the clock frequency. Amazon and Microsoft have used similar techniques in the past.

In fact, various cloud services company to consider transitional unity leap seconds to set for 24 hours. Google plans to transition when the next leap second 24-hour period, making the transition more gradual, consistent with other companies. Leap seconds time interval at present has not yet been determined, but that it estimated to be in the year 2018.

谷歌：允许任何机构使用NTP服务器，以应对2016年底闰秒 - IT资讯

北京时间12月1日消息，据外媒报道，谷歌将允许任何机构使用其NTP(网络时间协议)服务器，此举有助于IT组织应对2016年底的闰秒。

闰秒是为了保持民用时间与地球自转一致而设立的，对于普通人影响不大，但对依赖不同系统密切同步的应用和服务会造成严重影响。

大多数上网终端通过NTP获得授时。谷歌时间团队技术负责人迈克尔·希尔兹(Michael Shields)周三发表博文称，谷歌有自己的NTP服务器，利用它们帮助自己的系统应对闰秒。

普通操作系统不能应对闰秒，因此部分组织开发了专门方法，但有时这些专门方法本身会引发问题。谷歌一名代表称，过去部分谷歌系统在遭遇闰秒时曾出现罢工，虽然没有对其服务产生影响。

为此，谷歌将修改其NTP服务器，使之在闰秒前、后各10小时的期限内时钟频率降低0.0014%。自2008年的闰秒以来，谷歌一直使用这一技术。

采用这一技术的并非只有谷歌一家公司。Akamai计划在24小时的过渡期内放慢系统时钟频率。亚马逊和微软过去曾采用类似技术。

事实上，各大云服务公司考虑把闰秒过渡期统一设定为24小时。谷歌计划在下一次闰秒时采用24小时过渡期，使过渡更平缓，与其他公司保持一致。目前下一次闰秒时间尚未确定，不过谷歌估计是在2018年。
