Salt is time zone dependent

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Have 2 identical system in different time zones.

What is the expected output? What do you see instead?
You can't login into system

What version of the product are you using? On what operating system?
1.6.8 1.7

Please provide any additional information below.
I think in the UserGroupsUser.php you should use:

public function getSalt()
{
// turn the creation_date into the corresponding timestamp
list($date, $time) = explode(' ', $this->creation_date);
$date = explode('-', $date);
$time = explode(':', $time);

//with this command mktime will return identical value
date_default_timezone_set('UTC');

$timestamp = mktime($time[0], $time[1], $time[2], $date[1], $date[2], $date[0]);
// create the salt
$salt = $this->username . $timestamp;
// add the additional salt if it's provided
if (Yii::app()->controller->module->salt)
    $salt .= Yii::app()->controller->module->salt;
return $salt;
}

I think people might have problems when they upgrade module because salt might 
be change. Please, to think about it.
