Pressflow is a 100% api-compliant replacement for your standard Drupal Core. There are no database schema changes. So long as you are running a normal Drupal core and meet the other system requirements (PHP5.x, MySQL 5.x), Pressflow is a "drop in" replacement.

Field Datetime Time zone setting
Ref: http://drupal.org/node/767182

1. Site's time zone - When entering data into the field, the data entered is assumed to be in the site's time zone. When the data is saved to the database, it is converted to UTC. When retrieved from the database, the data is converted to the Site's time zone for annonymous users or the User's time zone for logged in users when User-configurable time zones is enabled.
2. Date's time zone - With this option enabled, the date field adds a select box to explicitly specify the time zone for the date entered. When the date is saved to the database, it is not converted & the time zone information is saved with the date. When retrieved from the database, no conversion is performed and the date is displayed exactly as entered.
3. User's time zone - When entering data into the field, the data entered is assumed to be in the user's time zone. When the data is saved to the database, it is converted to UTC. When retrieved from the database, the data is converted to the Site's time zone for annonymous users or the User's time zone for logged in users when User-configurable time zones is enabled.
4. UTC - When entering data into the field, the data entered is assumed to be in UTC time zone. When the data is saved to the database, it is converted to UTC (e.g. no conversion necessary). When retrieved from the database, the data is converted to the Site's time zone for annonymous users or the User's time zone for logged in users when User-configurable time zones is enabled.
5. No time zone conversion - The date entered is not converted when saved to the database. When retrieved from the database, the data is NOT converted and is displayed exactly as entered.

Access control of Views

It is possible that view will show the data that is not allowed to see by setting of permission.

Using PHP validation to the argument is very normal.

The php is look like the following:


global $user;
return arg(1) == $user->uid || user_access('access user profiles');

?>

Note:
users/2/edit
arg() is system-level item (not just views), and with the following values
arg(0) = 'users'
arg(1) = '2'
arg(2) = 'edit'



global  $user;
return db_result(db_query("SELECT GROUP_CONCAT(CAST(an.nid AS CHAR) SEPARATOR ',') FROM {acl_user} au INNER JOIN {acl_node} an ON au.acl_id = an.acl_id WHERE an.grant_view = 1 AND au.uid = %d", $user->uid));


?>


** Also refer to Views to display nodes based on ACL permission.
