说明：  数字电子时钟是一种使用数字电路技术实现时钟、分钟和秒钟定时的设备。 它在其他电子时钟中具有更高的准确性和主观性。数字钟包含扩展功能和基本功能。其中，基本功能部分：以数字形式准确定时，显示时、分、秒的功能; 扩展功能部分： 日期显示、闹钟、温度显示。(A digital electronic clock is a device that uses digital circuit technology to achieve clock, minute, and second timing. It has higher accuracy and subjectivity in other electronic clocks. The digital clock has two parts, basic functions and extended functions. Among them, the basic function part: accurate timing in digital form, display hours, minutes, seconds function; extended function part: date display, alarm clock, temperature display.)
