From 8f42f1292c2f1f1002b8446dc8b5351eb633d5ce Mon Sep 17 00:00:00 2001

Subject: r17526: Move timestamp generation into the objectGUID module.  It
 probably needs to be renamed (operation_add?).

This allows me to match the behaviour and substitute with the
entryUUID module for remote LDAP connections.
