From 860c46e76e21acef233ea6b22f4cf3f19ac662a6 Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Mon, 7 Mar 2011 01:35:51 +0000 Subject: Clean up date handling, as a first step to get rid of the frequent petty warnings in this area: - always store dates as strings, not as seconds since the Epoch - for input, try the three most common formats everywhere - for unrecognized format, just pass the date though verbatim - when there is no date at all, still use the current date Originally triggered by a one-line patch from Tim van der Molen, , which is included here.
