Thread: Unix dateformat ?

hi!

correct me, but is this possible postgresql doesn't contains any function
to convert date/datetime format to unix timestamp format?

in mysql I can do it with:

mysql> select unix_timestamp( now() ) as stamp;
+-----------+
| stamp     |
+-----------+
| 913710262 |
+-----------+

before I make any function in 'c', please if you know some solution inform
me,

    thanks,
    regards
        Redax

If I undestund what you want ... try this:

SELECT date_part('epoch', 'now'::datetime) as seconds;

This function returns:

  seconds
