Обсуждение: European Datestyle
Hello, Why is this happening ? ctonet=# show datestyle; NOTICE: DateStyle is ISO with European conventions SHOW VARIABLE ctonet=# select creation_date from users limit 1; creation_date ------------------------2000-12-07 04:40:23+01^^^^^^^^^^ Datestyle has been set either with -e and with "set datestyle" with no change. Context: Postgresql 7.0.3 on RedHat Linux 7.0 - Kernel 2.4.0-test10 - Glibc 2.1.94 and 2.2 Thanks! Bye! -- Daniele Orlandi

There are two ways of making dates make sense, none of them American (but hey, they're still using Fahrenheit, feet, lb, fl.oz. acres and other nonsensical units... ) -- Trond Eivind Glomsrød Red Hat, Inc.

Yes, it is; but according to the documentation (and how it used to be on other machines running PG 6.x) it should be ordered in european format, I don't know if I'm missing something obviuous or what... > There are two ways of making dates make sense, none of them American > (but hey, they're still using Fahrenheit, feet, lb, fl.oz. acres and > other nonsensical units... ) I do not mean to cricticize british units, after all, I would have preferred base16 units instead of base10 :) Bye! -- Daniele -------------------------------------------------------------------------------Daniele Orlandi - Utility Line Italia - http://www.orlandi.comViaMezzera 29/A - 20030 - Seveso (MI) - Italy -------------------------------------------------------------------------------

Please let me know what part was confusing and I can fix it for the next release. The default date style in 7.0 was changed from "Postgres" to "ISO". The euro vs US setting determines how *input* dates are interpreted, since they are not restricted to being only the format of the default output style. Use "set datestyle = 'Postgres,European'" to change to what you expect. You can set an environment variable or change the defaults when building the backend to get this always. There is an appendix in the docs discussing the parsing strategy, though it is all detail. - Thomas
