<?php
$d = new DateTime();
$dtz = ($d->getOffset())/3600;//returnt he difference between utc and local time
timeToSeconds($dtz);

function timeToSeconds($dtz)
{
     $timeExploded = explode(':', $dtz);

     if (isset($timeExploded[2])) {
         return $timeExploded[0] * 3600 + $timeExploded[1] * 60 + $timeExploded[2];//ccalculate it into seconds

     }
      $val=$timeExploded[0] * 3600 + $timeExploded[1] * 60;//return the seonds
      echo "Actual difference between utc and timestamp: ". $dtz."<br />";//the time difference in hours
      echo "The total second is: ".$val."<br />";//time difference in seconds
        $hours = floor($val / 3600);
        $mins = floor($val / 60 % 60);
        $secs = floor($val % 60);
        $timeFormat = sprintf('%02d:%02d:%02d', $hours, $mins, $secs);//convert seconds into H:i:s
        echo "After seconds to time ".$timeFormat."<br />";
        $dda=date("h:i:sa");//return the current timestamp
        echo "The current time is " . $dda."<br/>";
            $convert_current=strtotime($dda);//convert current timestamp
            $convert_utc=strtotime($timeFormat);//convert utc time
            echo "Convertion on current time: ".$convert_current."<br />";
            echo "Convertion on utc: ".$convert_utc."<br />";
                $minus=$convert_current-$convert_utc;//differentiate two time
                echo "The two difference in seconds: ".$minus."<br />";
                    $hours = floor($minus / 3600);
                    $mins = floor($minus / 60 % 60);
                    $secs = floor($minus % 60);
                    $correct = sprintf('%02d:%02d:%02d', $hours, $mins, $secs);//converting again it into H:i:s
                    echo "UTC time: ".$correct."<br />";

我正在尝试在：已访问和#two蓝色上建立#one黑色链接。当访问#two reverse应该应用#one应该是蓝色而#two应该是黑色。我试图将最后访问过的链接黑色和其他默认颜色着色。我试过了

<a href="#one"></a>
<a href="#two"></a>

我试图用CSS而不使用JS来实现这个目的。

Answer 1

a {
 color:blue;
}
a:visited{
  color:black;
}

基于兄弟姐妹链接的链接颜色：访问过
