Here is how I would do it

Names Default To Here( 1 );
dt = Current Data Table();
For Each Row(
	datetime = :date + 60 * 60 * Hour( :time ) + 60 * Minute( :time );
	datetime = datetime - In Hours( 1 );
	:new time = Hour( datetime ) * 60 * 60 + Minute( datetime ) * 60;
	:new date = Date MDY( Month( datetime ), Day( datetime ), Year( datetime ) );
);
