PP2 supports period datatypes. A period datatype is a datatype with two values that represent the start and end of a duration of time. The value that designates the beginning of the time period is included in the time span. The value that designates the end of the time period is not included in the time span. For example, a time period from February 1, 2006 to February 10, 2006 is nine days. The period includes February 1, 2006 and extends to, but does not include, February 10, 2006.

Any of these period datatypes can be used to insert data into, or retrieve data from, the database (for example, using INSERT or SELECT). The values returned from the database server (for example, using SELECT) are in the format described in the next sections.
