To combine date and time into a timestamp in Teradata

Suppose you have a table containing date and time columns like below,
Date1Time1
'2012-05-01''14:53:45'


if you want to combine the above fields into timestamp then,
SELECT Date1, Time1,
    CAST(  Date1 AS TIMESTAMP(0)) +
            (Time1 - TIME '00:00:00' HOUR TO SECOND) ts
 FROM Table;

Output:
Date1Time1ts
'2012-05-01''14:53:45''2012-05-01 14:53:45'
