Accurate Time with seconds

At 0900 45 678 the listener hears a time message followed by three pipes with a 1000 Hz beep.

Starting the third pipeline will mark the promised time. Repeat the message and cores at 10 second increments to make a total of six time messages so that a full minutes is always there. Among the objectives of this ministry is the dissemination of the New Zealand Time Standard to allow retraceable calibrations of chronographs and other watches.

In order to carry out such a recalibration, it is necessary to record at least two phone conversations to the speaking watch. There should be no distinction between the time intervals displayed by the speaking watch and those displayed by the watch in a contemporary quartz-controlled watch, unless the time intervals between phone conversations are several clear day.

You can find a manual with further information about the method of calibrating here. There are a number of Network Time Protocols (NTP) Strand 1 Server available for connection within New Zealand. The NTP is a default web interface for synchronizing computer time. An easier variant (called Simple Network Time protocol or SNTP), which is a subsets of NTP, is backed by the MSL server and can be used to adjust the time on any computer.

New Zealand's UTC(MSL) time standard is applied to the server by directly connecting one heart beat per second of signals. You can find further information on the use of the server here.

Most accurate watch ever produced will lose only one second every 15 billion years.

Researchers have established a new precision timing track and created an astronomical timepiece that never loses or gains a second in 15 billion years - a time greater than the universe's projected aging. Clocks measure the vibration of neurons to generate their "tick" and could one of these days become the default for Coordinated Universal Time (UTC).

Currently, nuclear thermometers (UTC) are used to determine the oscillation rate of the elements cesium, although they are only accurate in the range of one second in centuries of million years. Designed by the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder, the striking watch detects the motion of striking particles attached to a tight pillar with high-performance laser beams.

Of course, all atomic particles have a constant oscillation rate (about 430 trillion per second for strontium), and the measuring of these motions is used to generate the "tick" of the time. Known as the optic grating watch, the striking timepiece has been under construction for several years and has set new standards in timing since 2013.

A number of optimizations described in the Nature Communications magazine (including the screening of the watch against electro-magnetic radiation), however, have again made it three time more accurate. In fact, the watch is so accurate that a lift is only two inches from the earth's crust, which is apparent even if this tiny gravitational shift is recorded by the "tick" of the watch.

However, this is not just a question of showing off ("my watch is so accurate that it knows when you put a diary under it"), it could also help researchers produce incredible accurate mapping of the Earth' scape. Albert Einstein's principle of relative force initially forecast the influence of gravitation on the course of time.

This means, among other things, that the watches are ticking at different heights at different velocities. Researchers believe they can exploit this phenomena by using a web of unbelievably accurate watches distributed across the Earth's surfaces to gauge its form - a technique that bears the fantastical name of "relativistic geodesy".

However, at present not even the chronometer is accurate enough to surpass traditional earth measurements (scientists suggest that it would have to detect a height differential of only one centimetre to be useful). That means that the developers of the watch need only be happy with all the other positive benefits of more accurate timing, as well as the improvement of navigational and locational aids such as satellite tracking and the expansion of the limits of quantum mechanics.
