2006.14 is already the latest version. But I need to use numbers in versions, and the n is the 14th letter in the alphabet. Your code executes fine here:

derick@kossu:~$ export TZ=America/Sao_Paulo
derick@kossu:~$ date
Fri Oct 20 12:45:45 BRST 2006
derick@kossu:~$ php
<?php

echo "date_default_timezone_get: ".date_default_timezone_get()."\n";
echo "date('j-m-Y H:i:s TP'): ".date("j-m-Y H:i:s TP")."\n";

?>
date_default_timezone_get: America/Sao_Paulo
date('j-m-Y H:i:s TP'): 20-10-2006 11:45:57 BRT-03:00

I don't know what's wrong. See below.

-- php --
<?php

function parsePHPModules() {
 ob_start();
 phpinfo(INFO_MODULES);
 $s = ob_get_contents();
 ob_end_clean();
 
 $s = strip_tags($s,'<h2><th><td>');
 $s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);
 $s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);
 $vTmp = preg_split('/(<h2>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);
 $vModules = array();
 for ($i=1;$i<count($vTmp);$i++) {
  if (preg_match('/<h2>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {
   $vName = trim($vMat[1]);
   $vTmp2 = explode("\n",$vTmp[$i+1]);
   foreach ($vTmp2 AS $vOne) {
   $vPat = '<info>([^<]+)<\/info>';
   $vPat3 = "/$vPat\s*$vPat\s*$vPat/";
   $vPat2 = "/$vPat\s*$vPat/";
   if (preg_match($vPat3,$vOne,$vMat)) { // 3cols
     $vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3]));
   } elseif (preg_match($vPat2,$vOne,$vMat)) { // 2cols
     $vModules[$vName][trim($vMat[1])] = trim($vMat[2]);
   }
   }
  }
 }
 return $vModules;
}

echo "date_default_timezone_get: ".date_default_timezone_get()."<br>\n";
echo "date('j-m-Y H:i:s TP'): ".date("j-m-Y H:i:s TP")."<br>\n";
echo "system('date'): ";
system('date');
echo "<br>\n";
echo "<pre>\n";
$p = parsePHPModules();
print_r($p['date']);
print_r($p['timezonedb']);
echo "</pre>\n";

?>

Ok. i found the bug.

In timezonedb.c there's a one define that create timezonedb_external.

#define  timezonedb_builtin timezonedb_external

But in timezonedb.h he include timezonedb_idx_builtin and timelib_timezone_db_data_builtin. Because that need two more defines in timezonedb.c.

This bug has been fixed in CVS.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.

And thanks for your details on this!
