1.數(shù)碼管顯示
2.時(shí)間和日期每隔5秒自動(dòng)切換一次
3.數(shù)碼管顯示
4.可設(shè)置時(shí)間和日期
5.矩陣按鍵控制，可更改
6.自動(dòng)判斷閏年
1.按下切換按鍵可切換當(dāng)前顯示時(shí)間還是日期
2.按下設(shè)置按鍵進(jìn)入時(shí)間和日期的設(shè)置，設(shè)置哪一項(xiàng)，哪一項(xiàng)下面就會(huì)出現(xiàn)兩個(gè)點(diǎn)
3.再次按下設(shè)置按鍵即可推出設(shè)置繼續(xù)運(yùn)行
4.自動(dòng)判斷閏年
5.日期更正（比如當(dāng)前為5月31日，當(dāng)切換月份時(shí)，切換到6月，則天數(shù)自動(dòng)由31改為30）
