Earth Clock插件简介

Earth Clock插件描述

Ever surprised at when its no longer light out?  Or how early the sun has been rising?  Keep track of your day using a 24hour clock that displays the time of sunrise  sunset f cities all around the wld.  Since the hour h only rotates around the clock once per a day, easily see  underst proptionally how much time you have left in the day.

The hour  minute hs rotate counterclockwise.  This follows the convention of "East" on the right  "West" on the left, so the hour h rises in the mning on the right  sets in the evening on the left.  When the clock hits midnight, the hour h points straight down.  When the clock hits noon, the hour h points straight up.  Since the hour h starts the day pointing down, the minute h also tracks minutes starting pointing down as well  pointing straight up marks minute 30 of the hour.

Besides the day, the year is another natural, meaning notahumanconvention unit of time.  This clock will also help you visualize your year: the four circles under the clock track one quarter of the year each,  the proption they are filledin track how far youve gone through each quarter  together, the year.
