我们现在正在安克雷奇博物馆建造一个时钟，它反映了阿拉斯加几条主要河流的总流量，这些河流对当地和全球的环境变化都很敏感。
We're now building a clock at the Anchorage Museum that reflects the total flow of several major Alaskan rivers, which are sensitive to local and global environmental changes.
即使消费性电子商品也受到影响，例如全球定位系统必须考虑时间延滞，以修正人造卫星上时钟的速度。
Even consumer electronics is affected-the Global Positioning System must allow for time dilation, which alters the rates of clocks on its orbiting satellites.
同时，由于电脑的内置时钟不够精确，计时器亦会记录来自全球定位系统的报时讯号，以便准确计算宇宙射线的接收时间。
As the computer clock is not accurate enough, the timer card also records time beats from Global Positioning System (GPS). This makes accurate timing of cosmic ray arrival feasible.
