TIMESTAMP

For a bare TIMESTAMP, WITHOUT TIME ZONE is assumed.

The TIMESTAMP data type is available in Dialect 3 and Dialect 1.It comprises two 32-bit integers — a date-part and a time-part — to form a structure that stores both date and time-of-day.In Dialect 1, [fblangref50-datatypes-date] is an alias for TIMESTAMP.

The EXTRACT function works equally well with TIMESTAMP as with the Dialect 1 DATE type.

The TIMESTAMP (or synonym TIMESTAMP WITHOUT TIME ZONE) represents a time and date without time zone information.
