I'm using Pfeed(http://github.com/parolkar/pfeed) plugin for User
It creates PfeedItem model records and uses created_at field for a lot
of stuff inside.
Now I need to export/import those user logs. I do exporting to YAML.
When I reconstruct PfeedItem AR object from YAML, it have real(old)
creation time in created_at attribute. When I save this PfeedItem -
there is new created_at with current time written to database.
How do I force created_at to be not automatically generated, but
contain my old created_at timestamp from YAML?
