I disagree!
What would this do that would be non-standard? Does the SERIAL datatype add
something that is not standard? No... it just allows for an easy way to
implement something that is standard. The SERIAL "type" isn't really a
datatype, it's just a keyword that allows you to automatically specify an
int4 column with a related sequence and default. I don't see why the same
thing couldn't be done with TIMESTAMP!
I'm not saying to create an actual datatype that is called TIMESTAMP or
LAST_MODIFIED, just use it in a create script. It would then be implemented
with the DATE datatype combined with triggers.
Makes perfect sense to me!

BTW: I'm completely awake and I build applications specifically so I don't
have to do things by hand (ie. so I can be "lazy" or more efficient,
whichever you prefer).
