1、代码模板（直接套用）：找到站点目录文件 footer.php  添加即可。

    

<p>奇搜博客运行时长:<span id="sitetime" style="color:#096"></span></p>
<script>
    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(2019,2,29,10,15,45)
        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>
