Data Types in SQL - Timestamp
TIMESTAMP for values representing points in time on a specified uniform scale. DATE is used for timestamps on a scale of one day, such as DATE '2012-09-25' (a literal denoting September 25th, 2012). TIME is used for values denoting time of day only, such as TIME '16:30:00' (a literal denoting half-past four in the afternoon).
