Atomic Clock Current Time

Nuclear clock Current time

Official and standard time, as set by the. The Internet Time Service of the National Institute of Standards and Technology. Current world time is coordinated between atomic clocks around the planet.

Nuclear clock/current time

The Internet Time Service of the National Institute of Standards and Technology. ITS server ( is requested according to the Daytime Protocol (RFC-867). First line shows the precise answer given by the server. On the second line you can see the current date and time in humans. The standard results are in UTC/GMT (Coordinated Universal Time/Greenwich Mean Time).

Because of NIST overload limitations, the time displayed may not be accurate.

Time in the United States

December 28th is always the last weekend of the year. It can be described by the number of Thursdays: 12 weeks contain the Thursday of the year. On Thursdays, the weekly numbers in accordance with standard procedure are always the same as the year number. One benefit is that no seperate year such as the weekly index year is required, while the lexicographic order and chronic order remain the same.

The system is sometimes erroneously called the " Julyan date ", while the Juliet date is a continuous counting of the number of consecutive pages since date 0 from 1 January 4713 B.C. Greenwich midday, Juliet midday date (or midday on the date of ISO -4713-11-24, which uses the Gragorian midday calendar).

Base size is... referring to a zero cushion between 00 and 24 (where 24 is only used to represent late-night at the end of a given date).

Nuclear clock vs. local computer time base

A " starting time " is assigned to the instruments during initialisation. This means the time at which the instrument is to begin recording it. According to the starting time principle, the unit itself must receive a time basis. ActiLife will send the current time to the unit when a unit is initialised to act as a time basis.

There is a very precise quartz oszillator in the unit that starts to increase the time basis. It serves as the device's on-board clock until the unit is re-initialized. Though a certain clock rate deviation can be anticipated, it is minimized due to the high precision of the integrated quartz oszillator. As of ActiLife 6.5.0, the ActiLife 6.5.0 initiation monitor allows the user to choose between a time basis from the computer or an atomic clock.

You can toggle the selection by selecting the hypertext link to the right of the "Device Time" item as shown below: Once the LTC is chosen, the units are set with the computer's LTC as the time basis. If atomic time is chosen, ActiLife will attempt to collect the time basis from the United States National Institute of Standards and Technology (NIST) time server listing at .

First, ActionLife tries to connect to one of five arbitrary Trusted Netlist hosts from the hyperlinked lists. When a time is available, the computer's timezone shift adjustment is used to adjust the time. Minute and second presets directly from the kernel are used to complement the time basis.

When none of the five arbitrary server is available, the time basis is set to this time.
