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).
A mid-1940s alarm clock radio with AM radio stations only A typical 1980s clock radio featuring a digital clock/alarm and an analogue FM/MW/LW receiver.

[2] The longer the user stays in bed without moving, the louder and more intense the sound of the alarm will become.
It is also possible for quartz clocks and watches to have their quartz crystal oscillate at a higher frequency than 32 768 (= 2 15) Hz (high frequency quartz movements [4]) and/or generate digital pulses more than once per second, to drive a stepping motor powered second hand at a higher power of 2 than once every second, [5] but the electric ...
