In 1960, the International Radio Consultative Committee formalized the concept of UTC, and it was put into practice the year after. The transit circle is a part of the telescope's mechanics and it is still cited as the prime meridian's original reference (0° longitude). The reference line or starting point, the Prime Meridian, was determined to be the transit circle at the Royal Observatory in Greenwich, London. This is the basis for the 24-hour time zone system we know today.Īt the time, Greenwich Mean Time (GMT) was chosen as the world’s time standard. Universal Time (UT) was created at the International Meridian Conference in 1884. It is used to compare the pace provided by TAI with the actual length of a day on Earth.

UTC Global Clock wins full marks for depth and features although it's presentation and functionality let it down. There are plenty more elegant world time clocks for Mac, and anything that requires a calendar I'd use iCal or Google Calendar for anyway, although if you don't use any kind of organizer, you may find the extra functions useful. Overall, I wasn't really blown away by UTC Global Clock despite it's obvious depth. To access all of it's functions, you must go to your top menu bar where clicking on the time will reveal a drop down menu with a host of options from adding calendar reminders to configuring keyboard shortcuts. For example, as you go to wave your mouse over the time on the corner of your screen, it simply disappears for some strange reason. On a functional level though, it can be rather annoying. At it's most advanced, it can do everything from remind you to walk the dog to setting a stopwatch to record how much time you are working on a project. At it's most basic, UTC Global Clock will display and any world time zone in a corner of your screen.
