The purpose of this article is to describe the necessary background information to understand time and date issues on the Internet and in computer clocks.
Contents
Calendar standards
In the western world we are using the Gregorian calender which is a solar calendar following the seasons and the Earth's orbit around the Sun
- See the article Calendar standards
Time clock standards
The time clock are used to describe the time of the day and follows the Earth's rotation around itself. Each day representing one rotation of the Earth.
- See the article Time clock standards
Time standards
Time standards are used to coordinate the time internationally such as GMT, UT, UTC and TAI
- See the article Time standards
Computer time and date
A specific time includes a date and a clock time describing a specific Earth rotation around the Sun and specific Earth rotation around itself. The Earth's rotation around the Sun are influenced by it's elliptical orbit. The Earth rotation around itself called a solar day[1] are slowly decreasing, increasing the length of the day.
