From 2ab291e6c65ea1ad5ec70bef913e5fc4db3568b7 Mon Sep 17 00:00:00 2001 From: Denis Dzyubenko Date: Fri, 16 Apr 2010 11:36:59 +0200 Subject: Convert date/time format to something that Qt understands The date/time format in QLocale originate from unicode CLDR which has more format patterns that Qt understands, so when generating date for QLocale we remove unsupported patterns and convert some other to something that Qt understands.
