Second

Humans use two forms of 'second', though the most common one is the familiar one - 60 thirds, 1/60 of a minute, or the time it takes light to travel 299,792,458 meters in a vacuum (or a billion lens feet). It is also considered a unit of distance - if something is about a second away, it refers to a light-second or nearly 300 thousand kilometers.

The Arean calendar specifies extended seconds, minutes, and hours that are 1.027491251041666... times the length of their counterparts.
