$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";
    }
}
?>

Example #2 Set timezone to HONG-KONG


<?php

$options = array( "timezone" => "HONG-KONG");

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";
