数字钟的主要功能有年月日时分秒的显示输出功能和对日期及时间进行设置的功能，还可以有整点报时等功能。设计数字钟的核心问题是时钟日期的自动转换功能。即自动识别不同月份的天数的控制。据此可以设计一个如图所示结构的数字钟，该数字钟包括校时模块、月份天数处理模块、时分秒计时模块、年月日模块和输出选择模块。在本实验中，只进行了简单的数字时分秒设计，其他部分还有待下一步改进。
digital clock is the main function Minutes date when the output function and the date and time set for the function , they can point the entire timekeeping functions. Digital Clock Design is the core issue date of the clock automatic conversion function. Automatic identification is the number of days in the control. One can design a structure as shown in the digital clock, the digital clock module, including schools, the number of days in processing module, Minutes module at the time, date and output modules to choose modules.
