the code below...
-------------------------------
<?
function errorHandler($errno, $str, $file, $line)
{
//if ($errno == E_STRICT) return;
fwrite(STDERR, "\n\n$errno: $str\n\n");
if ($errno == E_USER_ERROR) die();
}
set_error_handler('errorHandler');

$a = mktime(14, 0, 0, 12, 20, 2005);
echo date('d/m/Y', $a);
?>
-------------------------------
....produces this STDERR...
-------------------------------
2048: mktime(): It is not safe to rely on the system's timezone
settings. Please use the date.timezone setting, the TZ environment
variable or the date_default_timezone_set() function. We selected
'Europe/Helsinki' for '2.0/no DST' instead

How can I silence it without commenting the commented line?

Thanks

Your server could be located in America, while your application is focussed
on European users, which can produce errors with date/time related
operations.

The fix is to follow the instruction and to apply the
date_default_timezone_set() function:

date_default_timezone_set('UTC');
$a = mktime(14, 0, 0, 12, 20, 2005);
echo date('d/m/Y', $a);

Instead of UTC, you can use any of the ones listed on the following page:

if (PHP_VERSION >= '5.1.0RC1')
date_default_timezone_set('Europe/Helsinki');
