Respond to updates to a node.
This hook is invoked only on the module that defines the node's content type (use hook_node_update() to act on all node updates).
This hook is invoked from node_save() after the node is updated in the node table in the database, before field_attach_update() is called, and before hook_node_update() is invoked.
Parameters
$node: The node that is being updated.

{node} table not actually updated!
hook_update gets invoked from within node_save(), which actually is wrapped in a transaction! Therefore the {node} table is not updated when hook_update is called. Don't query the table or, especially, don't call functions that rely on {node} table.
