The following is an example −
<?php
setlocale(LC_TIME, 'en_US');
echo strftime("%b %d %Y %H:%M:%S", mktime(20, 0, 0, 10, 20, 2017)) . "\n";
echo gmstrftime("%b %d %Y %H:%M:%S", mktime(20, 0, 0, 10, 20, 2017)) . "\n";
?>Output

<?php
echo(gmstrftime("%B %d %Y, %X %Z",mktime(20,0,0,11,30,91))."<br>");
setlocale(LC_ALL,"hu_HU.UTF8");
echo(gmstrftime("%Y. %B %d. %A. %X %Z"));
?>Output
