可以在手机上动态时钟代码吗
可以的，可以实时动态显示当前时间与当前日期，代码结构简洁、清晰、明了，（网络搜集，供参考）
知识的汇总：
1.HTML5
2.CSS3
3.JavaScript
重难点汇总：
1.各个指针的旋转角度的获取，首先要明确以下概念：
一周为360度、12小时、60分钟、60秒；
公式：一周的度数/一周的时间；
即得出时针每过一小时要旋转30度；
分针每过一分钟要旋转6度；
秒针每过一秒钟要旋转6度；
下面是代码部分：
HTML:
div id="box"
div id="h"/div
div id="min"/div
div id="s"div class="cen"/div/div
div id="data"/div
/div
CSS3:
body{
background-color: #aaa;
margin: 0px;
padding: 0px;
}
#box{
width: 400px;
height: 400px;
border-radius: 100%;
background: url(img/4706.jpg_wh860.jpg)0px 0px no-repeat;
background-size: 400px;
position: absolute;
left: 500px;
top: 200px;
}
#h{
width: 100px;
height: 10px;
background-color: red;
position: relative;
top: 195px;
left: 200px;
}
#min{
width: 140px;
height: 10px;
background-color: yellow;
position: relative;
top: 185px;
left: 200px;
}
#s{
width: 180px;
height: 10px;
background-color: blue;
position: relative;
top: 175px;
left: 200px;
}
.cen{
width: 10px;
height: 10px;
background-color: white;
border-radius: 100%;
}
#data{
position: relative;
top: 100px;
left: 150px;
color: red;
font-size: 20px;
}
JavaScript:
function tim(){
var d = new Date(),//获取当前系统时间
year = d.getFullYear(),//得到当前年份
mon = d.getMonth(),//得到当前月份
date = d.getDate(), //得到当前日期
hours = d.getHours(), //得到当前小时
minutes = d.getMinutes(), //得到当前分钟
seconds = d.getSeconds();//得到当前秒
var hou = "";
if(hours12){
hou = "下午";
}
else{
hou = "上午";
}
document.getElementById("data").innerHTML= year+"年"+mon+"月"+date+"日"+"
"+hou;
var n = document.getElementById("s");//获取秒针ID
n.style.transform = "rotate("+(seconds*6-90)+"deg)";//通过当前秒数，得到秒针旋转度数
n.style.transformOrigin = "left";//设置秒针旋转的基点
var i = document.getElementById("min");//获取分针ID
i.style.transform = "rotate("+(minutes*6-90)+"deg)"//通过当前分钟数，得到分针旋转度数
i.style.transformOrigin = "left";//设置分针旋转的基点
var h = document.getElementById("h");//获取时针ID
h.style.transform = "rotate("+((hours*30)+(minutes*0.5)-90)+"deg)"//通过当前小时数，得到时针旋转度数
h.style.transformOrigin = "left";//设置时针旋转的基点
}
setInterval("tim()",1000)
c语言怎么样编写一个时钟程序
c语言时钟程序代码如下：

#includemath.h
#define ID_TIMER 1//计时器ID

C语言是一门通用计算机编程语言，应用广泛。C语言的设计目标是提供一种能以简易的方式编译、处理低级存储器、产生少量的机器码以及不需要任何运行环境支持便能运行的编程语言。尽管C语言提供了许多低级处理的功能，但仍然保持着良好跨平台的特性，以一个标准规格写出的C语言程序可在许多电脑平台上进行编译，甚至包含一些嵌入式处理器（单片机或称MCU）以及超级电脑等作业平台。-时钟代码
C语言是由UNIX的研制者丹尼斯·里奇（Dennis Ritchie）于1970年 由 肯·汤普逊（Ken Thompson）所研制出的B语言的基础上发展和完善起来的。目前，C语言编译器普遍存在于各种不同的操作系统中，例如UNIX、MS-DOS、Microsoft Windows及Linux等。C语言的设计影响了许多后来的编程语言，例如C++、Objective-C、Java、C#等。-时钟代码
要个简单一点的小时钟代码~
这个是文字时钟代码:
script
var dayarray=new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday")
var montharray=new Array("January","February","March","April","May","June","July","August","September","October","November","December")-时钟代码
function getthedate(){
var mydate=new Date()
var year=mydate.getYear()
if (year 1000)
year+=1900
var day=mydate.getDay()
var month=mydate.getMonth()
var daym=mydate.getDate()
if (daym10)
daym="0"+daym
var hours=mydate.getHours()
var minutes=mydate.getMinutes()
var seconds=mydate.getSeconds()
var dn="AM"
if (hours=12)
dn="PM"
if (hours12){
hours=hours-12
}
if (hours==0)
hours=12
if (minutes=9)
minutes="0"+minutes
if (seconds=9)
seconds="0"+seconds
//change font size here
var cdate="smallfont color='000000' face='Arial'b"+dayarray[day]+", "+montharray[month]+" "+daym+", "+year+" "+hours+":"+minutes+":"+seconds+" "+dn-时钟代码
+"/b/font/small"
if (document.all)
document.all.clock.innerHTML=cdate
else
document.write(cdate)
}
if (!document.all)
getthedate()
function goforit(){
if (document.all)
setInterval("getthedate()",1000)
}
/script

具体的。。就是套用用几个函数算时间。。
不要对这种很长的东西害怕，其实大部分都是在画这个钟～
加油哦～
