常見(jiàn)例句Greenwich Mean Time updated with leap seconds. 用閏表來(lái)測(cè)定的格林尼治時(shí)間。For one, the leap second occurs in the middle of the day in Asia and Australia, causing a time hiccup during stock trading. 其中一個(gè)是，潤(rùn)秒發(fā)生在亞洲和澳洲的日間，時(shí)間會(huì)在貨運(yùn)進(jìn)行儅下“跳針”。US scientists want to change the current system, which keeps clocks in synch with solar time by adding a leap second every 18 months or so. 美國(guó)科學(xué)家希望改變現(xiàn)行系統(tǒng)，亦即透過(guò)每隔約18個(gè)月添增1閏秒，讓時(shí)鍾與太陽(yáng)時(shí)保持一致。Since 1999 until recently,the two time standards have been in close enough synch to escape any need to add a leap second,NIST said. 該協(xié)會(huì)說(shuō)，從1999年開(kāi)始到最近幾年，原子時(shí)和天文時(shí)一直処於同步狀態(tài)，所以不需要增加一個(gè)閏秒。Since 1999 until recently, the two time standards have been in close enough synch to escape any need to add a leap second, NIST said. 該協(xié)會(huì)說(shuō)，從1999年開(kāi)始到最近幾年，原子時(shí)和天文時(shí)一直処於同步狀態(tài)，所以不需要增加一個(gè)閏秒。Deciding whether and when a leap second is needed falls to an international organisation called the International Earth Rotation and Reference Systems Service (IERS). 決定是否需要閏秒、何時(shí)添加閏秒的任務(wù)由國(guó)際地球自轉(zhuǎn)事務(wù)中央侷（IERS）承擔(dān)。 返回 leap second
