[time-nuts] small multi-timezone display

Sat Jan 9 20:59:02 UTC 2021

For the curious, and if anyone wants to make it pretty, have a ball:

<?php
//$tz1 = "Europe/London";
$timestamp = time();

$tzs = explode(",", $_GET["tz"]);
$out_str="";
foreach( $tzs as $tz ){
  //echo $tz . "<p>\n";
  $dt = new DateTime( "now", new DateTimeZone( $tz )); //first argument
"must" be a string
  $dt->setTimestamp( $timestamp ); //adjust the object to correct timestamp
  $out_str .= $tz . ": " . $dt->format('d.m.Y, H:i:s') . "<p>\n";
}
//echo $dt->format('d.m.Y, H:i:s');
$sec=1;
?>
<html>
    <head>
    <meta http-equiv="refresh" content="<?php echo $sec?>">
    </head>
    <body>
    <?php
      echo $out_str;
    ?>
    </body>
</html>
