Atomic clocks are the most accurate timekeeping devices developed by man. Modern atomic clocks are so accurate that even in 100 million years less than a second of time would be lost.
This accuracy makes them ideal references for a NTP server (Network Time Protocol). NTP is a protocol widely used to synchronize computer networks across the Internet of local Area Network (LANs).
This article explains how to synchronise a computer network using NTP to an atomic clock source.
Atomic clocks are so accurate that a universal timescale has been developed called UTC (Coordinated Universal Time) that is based on the time told by atomic clocks. UTC is globally used and is the same everywhere enabling different computer networks to be synchronized to the same time.
Unfortunately atomic clocks are hugely expensive, extremely delicate and quite bulky pieces of equipment, so they are only really to be found in large scale physical laboratories or in highly technical pieces of equipment such as satellites.
Fortunately a dedicated NTP server can synchronize to UTC time using an atomic clock as a reference source by either making us of the national time and frequency transmissions or the GPS (Global Positioning System) network.
Many national physics laboratories such as NPL in the UK, NPL in Germany and NIST in the USA, broadcast a UTC time reference on long wave radio transmission. These signals can be picked up by a NTP server using a radio receiver. Unfortunately the radio transmissions are not broadcast by every country and the signals are finite.
Fortunately the constellation of satellites that make up the USA's GPS network all have an onboard atomic clock. This signal is used by satellite navigation receivers to work out location but can equally be used by a GPS NTP server as a timing source.
Using either a radio referenced NTP server or GPS time server, synchronization to within a few milliseconds of UTC is possible.
Richard N Williams is a technical author and specialist in atomic clocks, telecommunications, NTP and network time synchronisation helping to develop dedicated NTP clocks. Please visit us for more information about a network time server or other ntp server solutions.
Daily Time Clock Software: Easy Automation
Time and attendance of employees are monitored and tracked in many ways. In fact, there are a number of time clocks systems which can be bought from the market.
Some companies still use the paper and pencil approach to logging time and attendance in the company. This is considered to be a cheap and inexpensive means to clocking. Others use the punch clock where employees use the paper card which they would need to insert in the clock so that there time will be logged. Other companies use a more modern approach in clocking where magnetic cards are swiped in the system. Some even use the biometrics time, where a finger scan matching the employee will trigger information and thus time to be logged.
As for the getting the right system, this can be done by identifying first what the company requirements and needs are. This will make sure that important points in the company are considered by the system which will be acquired.
The daily time clock over time has gone through a number of developments. With the constant advancement came about a more modern and better approach to clocking. As a result, daily time clock software is born. This program is installed in the computers which employees need to access by logging in their codes or passwords. This system offers easy automation of the data which in effect makes it easier to generate reports. The daily time clock software also provides cost savings and minimizes human errors thus making information accurate and reliable.

How do i train myself to read in 24 hour clock (military time)?
Im so use to the 12 hour time, but i find it too confusing with AM and PM. Any tips for learning the 24 hour clock, so i don't have to keep converting in my HEAD!!
This is the most simple way for me hope it helps
...once I get into the teens I take away the (1) and subtract (2)
For example.... 13:00 take away the (1) would be 3:00 and subtract (2) gives you 1:00!
Or 17:45 take away the (1) would be 7:45 and subtract (2) gives you 5:45...
U get it?
Stone Breaks All-Time Wins Mark as Women's Hockey Tops Princeton
The No. 4 Crimson (19-6-5) scored four goals in the opening 15 minutes of play to cruise to a 5-1 victory over Princeton (13-13-4) at Bright Hockey Center—the 338th career win for Stone, who became the all-time winningest coach in NCAA women’s hockey history.
