SYSDATE in PostgreSQL !?

How can I define a table with columns with sysdate as the default value..

If there is no SYSDATE defined in PostgreSQL , what can I do ?

Any help is appreciated.


CREATE TABLE channels    (
 channelID                  NUMBER PRIMARY KEY,
 name                         VARCHAR2(64) NOT NULL,
 status                        INTEGER NOT NULL,
 remedyID                   VARCHAR2(15) UNIQUE,
 remedySchemaID       NUMBER default 48,
 remedyLastModified    INTEGER,
 updateTimeStamp      DATE default (SYSDATE),
 createTimeStamp       DATE default (SYSDATE)
);
