Facebook Announces That It Has Invented a New Unit of Time

Facebook has announced a new unit of time, called Flicks. "According to the GitHub page documenting Flicks, a Flick is 'the smallest time unit which is LARGER than a nanosecond,' defined as 1/705,600,000 of a second," reports The Verge. (For comparison, a nanosecond is 1/1,000,000,000 of a second, making a Flick roughly 1.41723356 nanoseconds long.) From the report: Now, you may be sitting there wondering what was wrong with regular seconds that Facebook had to go and invent its own unit, especially since the second is one of the few units that is universal across SI and imperial units. The name itself is a portmanteau of the phase "frame-tick," which is also why you might want to use them. Flicks are designed to help measure individual frame duration for video frame rates. So whether your video is 24hz, 25hz, 30hz, 48hz, 50hz, 60hz, 90hz, 100hz, or 120hz, you'll be able to use Flicks to ensure that everything is in sync while still using whole integers (instead of decimals). Programmers already use built in tools in C++ to manage these sorts of exact frame syncing, especially when it comes to designing visual effects in CGI, but the most exact timing possible in C++ is nanoseconds, which doesn't divide evenly into most frame rates. The idea to create a new unit of time to solve this problem dates back to last year, when developer Christopher Horvath posted about it on Facebook.
