根据 西狂部落阁 的文章提供的代码修改下样式，将代码放置在底部模板中或者你需要的地方(footer、sidebar 等等)，我这里的模板是 index.php 中。修改好其中自定义的网站建成时间和相关文字，就可以直接运行了。当然你可以修改 sitetime 的 CSS ,让它更有效果。
注意代码中的 “” ‘’ 引号，复制后要确保是英文状态下的，否则会出错。
1. <p>博客稳定运行<span style="color: orange;" id="sitetime"></span></p>
2. <script language=javascript>
3. function siteTime(){
4. window.setTimeout("siteTime()", 1000);
5. var seconds = 1000
6. var minutes = seconds * 60
7. var hours = minutes * 60
8. var days = hours * 24
9. var years = days * 365
10. var today = new Date()
11. var todayYear = today.getFullYear()
12. var todayMonth = today.getMonth()
13. var todayDate = today.getDate()
14. var todayHour = today.getHours()
15. var todayMinute = today.getMinutes()
16. var todaySecond = today.getSeconds()
17. /* 修改下面的t1数值为网站建成时间（年，月，日，时，分，秒）*/
18. var t1 = Date.UTC(2013,11,9,0,0,0)
19. var t2 = Date.UTC(todayYear,todayMonth,todayDate,todayHour,todayMinute,todaySecond)
20. var diff = t2-t1
21. var diffYears = Math.floor(diff/years)
22. var diffDays = Math.floor((diff/days)-diffYears*365)
23. var diffHours = Math.floor((diff-(diffYears*365+diffDays)*days)/hours)
24. var diffMinutes = Math.floor((diff-(diffYears*365+diffDays)*days-diffHours*hours)/minutes)
25. var diffSeconds = Math.floor((diff-(diffYears*365+diffDays)*days-diffHours*hours-diffMinutes*minutes)/seconds)
26. document.getElementById('sitetime').innerHTML = diffYears +' 年 '+ diffDays + ' 天 ' + diffHours + ' 小时 ' + diffMinutes + ' 分钟 ' + diffSeconds + ' 秒'
27. }
28. siteTime()
29. </script>
