thanks for replying,

I have my development database that contains the table test. well, to insert
records, comparing both tables and I see the difference in milliseconds that
were generated in each server. I need that times are exact, since we
have a procurement
system for auction, which requires the milliseconds, and that can make a
difference to any bidder wins the bid.
the truth is that it's random, I went back to try and generate some logs me
equal, and others have differences in milliseconds

CREATE TABLE test
(
  id bigserial NOT NULL,
  namecharacter varying(200),
  alta timestamp without time zone DEFAULT now(),
  mod timestamp with time zone DEFAULT now()
)
WITH (
  OIDS=FALSE
);

 insert into test(name) values('first test');
