WordPress DUX主题网页底部添加网站运行时间简单方法，纯代码实现

先看看效果图：

DUX主题设置也比较方便，直接在后台“外观——DUX主题设置——自定义代码——自定义网站底部内容”粘贴以下代码即可。相对于修改主题文件，在后台设置，除了简单方便外，还可以免于在升级主题重新设置的麻烦。

网站已平稳运行：<span id="sitetime"style="color: #24a0f0;"></span>
<script language=javascript>
function siteTime(){
window.setTimeout("siteTime()", 1000);
var seconds = 1000
var minutes = seconds * 60
var hours = minutes * 60
var days = hours * 24
var years = days * 365
var today = new Date()
var todayYear = today.getFullYear()
var todayMonth = today.getMonth()
var todayDate = today.getDate()
var todayHour = today.getHours()
var todayMinute = today.getMinutes()
var todaySecond = today.getSeconds()

var t1 = Date.UTC(2014,7,14,9,22,00) <!--注意：月份是0-11,所以需要把建站月份减一-->
var t2 = Date.UTC(todayYear,todayMonth,todayDate,todayHour,todayMinute,todaySecond)
var diff = t2-t1

var diffYears = Math.floor(diff/years)
var diffDays = Math.floor((diff/days)-diffYears*365)
var diffHours = Math.floor((diff-(diffYears*365+diffDays)*days)/hours)
var diffMinutes = Math.floor((diff-(diffYears*365+diffDays)*days-diffHours*hours)/minutes)
var diffSeconds = Math.floor((diff-(diffYears*365+diffDays)*days-diffHours*hours-diffMinutes*minutes)/seconds)
document.getElementById("sitetime").innerHTML=diffYears+" 年 "+diffDays+" 天 "+diffHours+" 小时 "+diffMinutes+" 分钟 "+diffSeconds+" 秒"
}
siteTime()
</script>
