MS SQL server has a different terminology I think. They use DATETIME to
indicate the equavalent of a postgres TIMESTAMP. In sql server timestamp is
a read only type that is set by the server. Anytime the row is updated or
on insert it puts in a timestamp.

Some people have indicated that perhaps this does not belong in the core
because it's easily achieved with triggers and I think they have a point
but maybe what's really needed are domains. Not just your average every day
domains but supercool domains with triggers!.

that way you can define a domain called UPDATED using a timestamp field and
a insert or an update trigger perhaps even a default value or a check. This
would make it easier to insert the same rules and triggers into every table
just by adding a field with the defined domain.

Interbase support domains which let you define checks and defaults but not
triggers. I know this kind of grandiose but it would be cool.
