BRG welcomes requests for customized time zone displays to meet your individual needs. Analog clocks are available in 12" and 15" diameters and Brushed Aluminum or Black Plastic Finishes. You can feature up to 18 different time zones, 15 and 30 minute offsets, including DST rules. There is an auto brightness option that allows the display intensity to automatically adjust LED brightness to ambient light.īRG also offers a Wireless 2.4 GHz analog Time Zone Display for retro look. For indoor use, the intensity can be reduced for normal viewing, or increased for greater viewing distance. The standard high brightness bar segment displays are ideal for indoor applications, but they cannot be seen in direct sunlight, or highly reflected sunlight. The digital zone labels are available in Red, Green and Yellow. Digital bar segments are available in Red, Green and Blue LEDs. Specify custom lettering from left to right when ordering. Programming and time is maintained during power outages.įor those that require external time sources, we offer GPS, NTP (Network), IRIG-B, and SMPTE time receivers to synchronize the time zone display with the U.S. High Reliability.įactory synchronized with the U.S. Additionally, clocks using matrix characters for time or location label, you can also display the Military shipping code and Air Tasking Order (ATO).Īccurate for Life – no manual adjustments are required for the life of the display. You can display more than just time on BRG time zone displays - For clocks with bar segment digits, any zone can be configured to display the Julian Day/Date, Sunrise time, Sunset time, temperature, configurable fixed numbers and more. An IR remote control is included with all digital time zone displays. If a country changes daylight saving time rules, the change can easily be implemented in the field without the need for factory programming or firmware updates.ĭigital time zone displays will provide any combination of time zone and display formats, including UTC (Zulu) Time, Any World Time Zone, Half-hour time zones, Enable or Disable Daylight Saving Time, and 12 or 24 hour display formats, with or without leading zeros. If all this talk about time has got you in a spin, why not visit the Royal Observatory for yourself? Explore the home of Greenwich Mean Time, and find out more about the mysteries of space at London's only planetarium.BRG digital time zone clocks are capable of displaying all known world time zone rules, including rule based daylight saving time, 30 minute time zones, and more. For the first time, cities from London to Glasgow to Belfast could share exactly the same time.īy 1866 Observatory time was even being sent to the United States, with transatlantic submarine cables connecting Greenwich with Harvard University in Massachusetts. The Shepherd Gate Clock was linked to the main ' motor clock' inside the Royal Observatory, which from 1852 to 1893 was the central clock that determined the whole British time system.īy using telegraph wires, the time determined by this highly accurate Observatory clock could be shared across the country. If you want to confuse your friends, you can own your very own replica version.īut this clock has another secret. That means that the hour hand goes round only once in every 24 hours.Īt 12 noon, instead of pointing straight up, the hour hand points straight down at XII. Instead of the usual numbers 1-12 on its clock face, it has 24 Roman numerals. This is the Shepherd Gate Clock, which since 1852 has been installed outside the gates of the Royal Observatory Greenwich. At 12 midnight it also neither am nor pm. It is therefore neither 'ante' (am) nor 'post' (pm) meridiem. pm stands for post meridiem or "after midday" – after the sun has crossed the meridian.Īt exactly 12 noon, the Sun is at its highest point in the sky and directly over the meridian.This is the time before the sun has crossed the meridian. am stands for the Latin ante meridiem, translating to "before midday".The 12-hour clock divides the 24-hour day into two periods. To avoid any confusion (and to make sure you arrive on time), it might be best to say 12 noon or 12 midnight instead.Īlternatively, you could use the 24-hour clock system, where 12:00 is noon and 00:00 (or 24:00) is midnight. While most people follow this convention, technically it's not quite right – as you'll see from the definition of am and pm below. When they say 12am, they normally mean 12 midnight. When most people say 12pm, typically they're talking about the middle of the day: 12 noon. Well, maybe not, especially if you're using a 12-hour clock. ‘Midnight ’ refers to 12 o’clock during the night. Simple right? 'Noon ' means 'midday' or 12 o’clock during the day.
