Code

function date_timezone_user($op, &$edit, &$account, $category = NULL) {
  if (isset($account->uid) && $op == 'login' && variable_get('configurable_timezones', 1)) {
    if (strlen($account->timezone_name)) {
      $date = date_now($account->timezone_name);
      $offset = date_offset_get($date);
      if ($offset != $account->timezone) {
        $account->timezone = $offset;
        db_query("UPDATE {users} SET timezone='%s' WHERE uid = %d", $offset, $account->uid);
      }
    }
    else {

      // If the user doesn't already have a timezone name selected,
      // default it to the site timezone name and offset.
      $timezone = variable_get('date_default_timezone_name', NULL);
      if (!empty($timezone)) {
        $date = date_now($timezone);
        $offset = date_offset_get($date);
        db_query("UPDATE {users} SET timezone_name = '%s', timezone='%s' WHERE uid = %d", $timezone, $offset, $account->uid);
      }
    }
  }
