javascript - postgresql to_timestamp returns different date than represented by the timestamp -

here's replication of problem:

i timestamp of via javascript as

 var ts = +new date // 1368971991090 console.log( new date(1368971991090) ); // sun may 19 2013 13:59:51 gmt+0000 (gmt)

in postgres console,

# select to_timestamp(1368971991090);           to_timestamp           --------------------------------  45350-12-30 05:31:29.999872+00 (1 row)

a date way future.
the docs of javascript date#gettime returns milliseconds starting epoch; same argument type postgres' to_timestamp accepts. java's date#gettime returns same value js date#gettime.

quote postgresql doc link:

it accepts double precision argument , converts unix epoch (seconds since 1970-01-01 00:00:00+00) timestamp time zone.

key -

seconds since

and in js doc:

number of milliseconds since 1 january 1970 00:00:00 utc
