本数字钟可实现正常计时，支持12小时和24小时两种计时方式的切换，允许用户手动调时和整点报时功能。
系统对外向用户提供了两个按键:功能键和调整键.功能键用于功能选择,调整键用于相关的时间调整. 当接通电源后系统便开始正常计时，如果按一下功能键，则进入调小时模式,再按一次则进入调分模式,再按则进入12/24小时模式选择设定,再按则恢复到正常计时状态. 在正常计时状态下，用户可以选择12或24小时的计时方式，第六个数码管的右下方小点亮表示是12小时模式，不亮表示24小时。整点报时时，六个数码管的小点会同时亮。
当用户通过按键进入校时状态时，第二个数码管的小点变亮，表示现在在对小时进行设置；同样，进行校分状态时，第四个数码管的小点会亮，表示现在正在对分钟进行设置。
