 * 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 :)
 *
 * Revision 1.1  1997/04/10 16:53:30  mjl
