longitude in time

基本解釋

GMT is a universal time zone, based on the Greenwich meridian corrected by the longitude of the location in which the time is set.
GMT是一種通用時(shí)區(qū)，是根據(jù)格林威治子午線，用設(shè)定時(shí)間所在位置的經(jīng)度與其求差計(jì)算出來(lái)的。
Different countries in the world where the longitude location, the time of all countries are different, so the "new year" date is different.
世界各國(guó)所處的經(jīng)度位置不同，各國(guó)的時(shí)間也不同，所以各國(guó)“過(guò)年”的日期也不同。
Because of the longitude of the world in different locations, countries of time is also different, accordingly, "new date there are also different."
由于世界各國(guó)所處的經(jīng)度地位不同，各國(guó)的時(shí)間也不同，因而，“除夕”的日期也有不同。

The clock could tell the correct time in two places, meeting the requirements for learning longitude on the sea.

As a seafaring nation, Britain depended on accurate navigation, and determining longitude on the open ocean depended on comparing local time to the time in a place where the longitude was known.
