One leaf falls each half-hour, at approximately 25 and 55 minutes after the hour. A different design features 60 leaves with the numbers 1 to 12 repeated in fives, each leaf falling after 12 minutes. The disadvantage of this is that 24-hour clocks cannot use this design, nor there is a way to show "AM" or "PM" information in a 12-hour design.
A flick is a unit of time equal to exactly 1/705,600,000 of a second.The figure was chosen so that time periods associated with frequencies commonly used for video or screen frame rate (24, 25, 30, 48, 50, 60, 90, 100 and 120 Hz), as well as audio sampling (8, 16, 22.05, 24, 32, 44.1, 48, 88.2, 96, and 192 kHz), can all be represented nicely with integers.

Digital clocks typically use the 50 or 60 hertz oscillation of AC power or a 32,768 hertz crystal oscillator as in a quartz clock to keep time. Most digital clocks display the hour of the day in 24-hour format; in the United States and a few other countries, a commonly used hour sequence option is 12-hour format (with some indication of AM or PM).
For display on computers, technology such as the animated GIF and Flash animation were developed. In addition to short films, feature films, television series, animated GIFs, and other media dedicated to the display of moving images, animation is also prevalent in video games, motion graphics, user interfaces, and visual effects.

After winding, the arbor is stationary and the pull of the mainspring turns the barrel, which has a ring of gear teeth around it. This meshes with one of the clock's gears, usually the center wheel pinion and drives the wheel train. The barrel usually rotates once every 8 hours, so the common 40-hour spring requires 5 turns to unwind completely.
Lavet-type stepping motor of a quartz clock. A black rotor sprocket provides the mechanical output. The Lavet-type stepping motor has widespread use as a drive in electro-mechanical clocks [1] and is a special kind of single-phase stepping motor. Both analog and stepped-movement quartz clocks use the Lavet-type stepping motor (see Quartz clock).
