How it works
We use NTP (network time protocol),
the accuracy of NTP is 0,232 nanosecond loss each 136 years ! |

Time displayed is UTC the official time reference. UTC replaced Greenwich Mean Time on January 1, 1972 as the basis for the main reference time scale Coordinated Universal Time is abbreviated UTC. UTC is derived from International Atomic Time (TAI), which is a time scale tracking proper time on the rotating surface of the Earth Most UTC days contain exactly 86,400 SI seconds, with exactly 60 seconds in each minute. However, since the mean solar day is slightly longer than 86,400 SI seconds, occasionally the last minute of a UTC day will have 61 seconds adding a leap second. A leap second is an intercalary, one-second adjustment that keeps broadcast standards for time of day close to mean solar time. Broadcast standards for civil time are based on Coordinated Universal Time (UTC), a time standard which is maintained using extremely precise atomic clocks. To keep the UTC broadcast standard close to mean solar time, UTC is occasionally corrected by an intercalary adjustment, or "leap", of one second. The timing of leap seconds is determined by : the International Earth Rotation and Reference Systems Service (IERS).
