looks like you using the following code for showing the date:
php:
<?php
echo(date('d-m-y | H:i:s a T'));
?>
this will use the timezone that the server is set to;
to change the timezone used, you could change that to:
php:
<?php
date_default_timezone_set('Australia/Perth');
echo(date('d-m-y | H:i:s a T'));
?>
a list of availabel time zones can be found here:
timezones.php
