The problem is that the datetime entry is generating the same time values in
the transaction. You do not want that as your primary key. You can still
create an index on the value, but if two (or more) rows are ever inserted in
the same transaction or even at the exact same time your primary key will be
invalid.
If you can't recreate the table with another primary key the just drop the
index. You can create a new index with the CREATE INDEX statement.
