Обсуждение: function for current date-time

Hi,
I have a timestamp field in my table and want to set a default value of current date/time for it.
What should i enter as its default value? is there any function like now() in postgres?

Thanks,
~Harpreet

Yes, now() ;-)

test=# create table foo (id int, ts timestamp default now());
CREATE TABLE
test=# insert into foo (id, ts) values (1, default);
INSERT 0 1
test=# select * from foo;
 id |            ts
