Facebook Oculus invented a new time unit called the ‘flick’

A flick (frame-tick) is a very small unit of time. It is 1/705600000 of a second, exactly.

1 flick = 1/705600000 second

Here’s a list of numbers into which 1/706,600,000 divides evenly: 8, 16, 22.05, 24, 25, 30, 32, 44.1, 48, 50, 60, 90, 100, 120.


Motivation

When working creating visual effects for film, television, and other media, it is common to run simulations or other time-integrating processes which subdivide a single frame of time into a fixed, integer number of subdivisions. It is handy to be able to accumulate these subdivisions to create exact 1-frame and 1-second intervals, for a variety of reasons.

Knowing that you should never, ever use floating point representations for accumulated, simulated time (lest your temporal accuracy degrade over time), the std::chrono time tools in C++ are ideal. However, the highest usable resolution, nanoseconds, doesn't evenly divide common film & media framerates. This was the genesis of this unit.
