You can find not less than 6 satellite navigation programs, all of which function by transmitting time signals. Of the only real two satellite devices with world-wide protection, GPS calculates its time signal from an epoch, Whilst GLONASS calculates time being an offset from UTC, Along with the UTC input adjusted for leap seconds.

(Sometimes the term 'equinox' may very well be made use of by yourself, e.g. where it is obvious with the context to end users of the information during which form the thought of astronomical variables are expressed, in equatorial sort or ecliptic type.)

In chronology and periodization, an epoch or reference epoch is An immediate in time picked out because the origin of a selected calendar era. The "epoch" serves as being a reference position from which period is calculated.
In computing, an epoch is a fixed date and time used for a reference from which a pc measures program time. Most Laptop or computer systems decide time for a quantity symbolizing the seconds removed from a specific arbitrary date and time. As an illustration, Unix and POSIX evaluate time as the number of seconds that have passed considering that Thursday one January 1970 00:00:00 UT, a point in time often known as the Unix epoch.
