-- The following changes the last_modified column from a TIMESTAMP to a
-- TIMESTAMP WITH TIME ZONE.  It copies over existing values of last_modified.
-- 
-- CAUTION:  This assumes that the values of the original 'last_modified'
-- column were in the *local time zone*.
--
-- If you find that the original values in 'last_modified' are in *UTC*,
-- (and this is not your local time zone), you will need to convert the
-- values of your last_modified column to your local time zone in order
-- for the following code to work.
