博客运行时间统计代码

JS版

    <script>
    function secondToDate(second) {
        if (!second) {
            return 0;
        }
        var time = new Array(0, 0, 0, 0, 0);
        if (second >= 365 * 24 * 3600) {
            time[0] = parseInt(second / (365 * 24 * 3600));
            second %= 365 * 24 * 3600;
        }
        if (second >= 24 * 3600) {
            time[1] = parseInt(second / (24 * 3600));
            second %= 24 * 3600;
        }
        if (second >= 3600) {
            time[2] = parseInt(second / 3600);
            second %= 3600;
        }
        if (second >= 60) {
            time[3] = parseInt(second / 60);
            second %= 60;
        }
        if (second > 0) {
            time[4] = second;
        }
        return time;
    }
</script>
<script type="text/javascript" language="javascript">
    function setTime() {
        // 博客创建时间秒数，时间格式中，月比较特殊，是从0开始的，所以想要显示5月，得写4才行，如下
        var create_time = Math.round(new Date(Date.UTC(2021, 1, 22, 0, 0, 0))
                .getTime() / 1000);
        // 当前时间秒数,增加时区的差异

    setInterval(setTime, 1000);
