使用带有节点postgres的流中的COPY使用Postgres日期

Question

I have the following table in PostgreSQL:

CREATE TABLE history (
    request_date timestamp without time zone DEFAULT now() NOT NULL,
    user_id uuid,
    client_id character varying(255),
    resource character varying(255) NOT NULL,
    latency integer NOT NULL
);

I am using node-postgres to perform a COPY FROM task. This is what I have so far:

var pg = require('pg');
var copyFrom = require('pg-copy-streams').from;
var Readable = require('stream').Readable;

pg.connect(config.database.connection, function(err, client, done) {
  var stream = client.query(copyFrom('COPY history FROM STDIN WITH NULL as \'null\''));
  var rs = new Readable;

  rs.push(new Date() + '\tnull\tnull\t"' + req.originalUrl + '"\t' + responseTime);
  rs.push(null);
  rs.on('error', done);

  rs.pipe(stream).on('finish', done).on('error', function (err) {
    console.log(err);
    done();
  });
});

But I am having problems with the date (first column), I dont know what is the format needed by Postgres and I am getting the following error:

{ [error: time zone "gmt-0300" not recognized]
  name: 'error',
  length: 175,
  severity: 'ERROR',
  code: '22023',
  detail: undefined,
  hint: undefined,
  position: undefined,
  internalPosition: undefined,
  internalQuery: undefined,
  where: 'COPY history, line 1, column request_date: "Thu Feb 19 2015 09:51:47 GMT-0300 (ART)"',
  file: 'datetime.c',
  line: '926',
  routine: 'DecodeDateTime' }

What should be the correct way to pass that date?

Answer 1

new Date().toUTCString() did the trick:

rs.push(new Date().toUTCString() + '\tnull\tnull\t"' + req.originalUrl + '"\t' + responseTime);

and then it works :)
