Editing timestamps?

Hi, I'm redeveloping an old site for someone and want to import all
their old news archives into my database. They were previously stored
as text in the html so I'm having to cut and paste each story, so
everything is timestamped with today's date. What's the easiest way to
edit the timestamp so I can change it to the date it was originally
created?

Thanks

There are a couple of ways you can do this. If you have access to the
database, you can probably export and re-import the data wholesale
(but you said the articles are in HTML). If you're OK with cut-and-
paste, you can always edit the timestamps manually in the new database
and change them to the old values.
