* Revision 1.2 1997/04/17 13:50:57 scrappy
* From: "Martin J. Laubach" <mjl@CSlab.tuwien.ac.at>
* Subject: [HACKERS] Patch: set date to euro/us postgres/iso/sql
*
* Here a patch that implements a SET date for use by the datetime
* stuff. The syntax is
*
* SET date TO 'val[,val,...]'
*
* where val is us (us dates), euro (european dates), postgres,
* iso or sql.
*
* Thomas is working on the integration in his datetime module.
* I just needed to get the patch out before it went stale :)
