$options = array( "date_format" => INGRES_DATE_ISO4 );
if (ingres_set_environment($link, $options))
{
$result=ingres_query($link,"select date('now') as date");
while ( $object = ingres_fetch_object ($result) ) {
echo $object->date."\n";
}
}
?>
Przykład #2 Set timezone to HONG-KONG
<?php
$options = array( "timezone" => "HONG-KONG");
if (ingres_set_environment($link, $options))
{
