Dick,
Will I be right in assuming that while table with columns of type
"timestamp with local Timezone" will not be affected but tables with
"date" columns and hence the application be affected? Even in 10g
there must be some tables with column type "date" and so it may have
some impact (like Mladen implies).
Thanks.
