I don't know of any hack that could help you with this. The only thing i can think of, is to edit the following code in your ./includes/init.php, and adjust the time. But not sure if that would be enough to change everywhere.
PHP Code:
// start the page generation timer
$pagestarttime = microtime();
define('TIMESTART', microtime());
// set the current unix timestamp
define('TIMENOW', time());
By best advice would be to change hosts.
