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.
Held every September just north of Reno, the National Championship Air Races have become something of a northern Nevada tradition, drawing aviation enthusiasts from around the globe. During the course of a week, the lush desert plains north of Reno play host to hundreds of aircraft, their pilots and crews, and spectators. The event showcases six racing classes, a formidable display of static aircraft, and several military and civilian flight demonstrations.
Through the use of a Stratum 1 NTP server, it is possible to produce surveillance videos with timestamps legally-traceable to UTC. This solution is far more cost-effective and accurate than others, and has quickly become the preferred option for video surveillance applications.
A GPS NTP server synchronizes to precise time from GPS satellites and operates securely behind a firewall to synchronize all elements of a system, down to the millisecond. Indeed, such servers typically have a margin of error of just plus or minus two milliseconds, which is more than accurate enough for successfully defending time-stamped evidence in a court of law.
Masterclock’s new time zone clocks can be combined to create a unique time zone display. Each clock can be customized with red, blue, green, amber, or white* (*time line only) LEDs, with a 4- or 6-digit time line and an 8-digit alpha display on the top or bottom. The clocks' small foot print minimizes required wall space while providing a clean viewing distance with 2.3-inch (5.8 cm) numeric and alpha digits.
