"A flick (frame-tick) is a very small unit of time. It is 1/705600000 of a second, exactly.
1 flick = 1/705600000 second
This unit of time is the smallest time unit which is LARGER than a nanosecond, and can in integer quantities exactly represent a single frame duration for 24 Hz, 25 Hz, 30 Hz, 48 Hz, 50 Hz, 60 Hz, 90 Hz, 100 Hz, 120 Hz, and also 1/1000 divisions of each, as well as a single sample duration for 8 kHz, 16 kHz, 22.05 kHz, 24 kHz, 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, and 192kHz, as well as the NTSC frame durations for 24 (1000/1001) Hz, 30 * (1000/1001) Hz, 60 * (1000/1001) Hz, and 120 * (1000/1001) Hz.*
That above was one hell of a run-on sentence, but it's strictly and completely correct in its description of the unit.
This makes flicks suitable for use via std::chrono::duration and std::ratio for doing timing work against the system high resolution clock, which is in nanoseconds, but doesn't get slightly out of sync when doing common frame rates."
