We did this for our app... we're always on FreeBSD though, but I imagine
the same files exist on Linux/others just somewhere else...
define("ZONETAB", "/usr/share/zoneinfo/zone.tab");
$fd = @fopen(ZONETAB, "r");
if (!$fd) {
print("<option value='GMT'>GMT");
} else {
while (!feof($fd)) {
$line = fgets($fd);
if (ereg("^US\t", $line)) {
list($x, $x, $tz_file, $tz_name) = explode("\t", trim($line));
print("<option value='$tz_file'>$tz_name");
}
}
fclose($fd);
}
Gives you a kind of odd format though (we needed the actual timezone file name,
not the offset), but maybe this gets you closer...
