Accurate timing and synchronization can be accomplished in many ways. While your specific choice of technique depends on your requirements, adhering to proven standards make your systems more practical, robust, and scalable. Here’s why you may want to consider employing IRIG-B time codes.
Maintaining accurate time is key in the travel industry, especially in airport terminals and air traffic control systems. Airports and airlines are particularly busy during summer and holiday vacation periods, which is stressful for workers as well as passengers. Having correct airport terminal clocks and in-sync air traffic control systems is essential. One way to reduce stress, prevent delays, and ensure smooth transportation schedules is to maintain precise time synchronization.
In today's economic world, the word on the tip of all of our tongues is "globalization." Long before the days of traveling distance by train, the people of the world explored the furthest reaches of our planet to discover the many cultures and customs of those lands. However, with expedited mass transit came the need for our world to begin solving a very fundamental problem in travel logistics: "What time is it?"
From SCADA (supervisory control and data-acquisition) systems to PLCs (programmable-logic controllers), industrial automation includes a vast range of control systems. These systems manage everything from automotive part production to food processing, and they rely on synchronizing several devices at once. Although synchronization and timing are never perfect, steady results are possible with the right equipment. Learn more about synchronization with hardware-based Ethernet protocol solutions.
Since we started adding Leap Seconds in 1972, there have been 26 of them - with the 27th to follow at 11:59:59 p.m. UTC (6:59:59 p.m. ET) on Dec. 31, 2016. The most recent addition occurred on June 30, 2015, which was the first since 2012 and the second since 2008. None were added from 1999-2004, but one was added every year with only five exceptions from 1973-95.
In April 2016, the Securities and Exchange Commission approved a proposed rule change from the Financial Industry Regulatory Authority to tighten rules for clock synchronization at National Market System securities and over-the-counter equity securities firms. It's important for these companies to understand the changes and to have the right Network Time Protocol servers to maintain compliance. Firms have until Feb. 20, 2017 to comply.
