Hi there,
I'd like to format a time stamp with time zone as ISO pattern (e.g.
1999-01-08 04:05:06 -8:00)
I found the patterns for all the timestamp parts, from "Data Type Formatting
Functions" Postgresql documentation, excepting the numeric ISO time zone.
Please suggest the appropiate pattern for that.
TIA,
Sabin

Have you tried the default PgSQL behaviour, without setting DateStyle, or
doing any explicit formating?
Maybe its exactly what you want.
What does
select now();
from within psql, output in your system?

If your DateStyle is set to ISO that's the default format. You don't
need to use to_char()
Or am I missing your point?

Hi Richard,
I'd just like to format it independent of my DateStyle. Some timestamp parts
may be formatted this way.
For instance I can format ISO date with to_char( dt, 'YYYY-MM-DD'), and ISO
time with to_char( dt, 'HH24:MI:SS') as well. I'd just like to find the
format pattern for the ISO time zone (numeric).
Regards,
Sabin

Hmm - we don't seem to support those codes (TZH, TZM) for some reason.
http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/sql_elements004.htm#sthref405
But it seems the developers know about it:
http://www.postgresql.org/docs/faqs.TODO.html
http://archives.postgresql.org/pgsql-hackers/2005-12/msg00948.php
If you know a little bit of "C" then you should be able to submit a
patch for this without too much trouble.
For the moment, you'll have to use extract() to pick out the bit(s) you
need:
to_char(extract(timezone_hour from current_timestamp), 'S00');
