ISO 8601

http://en.wikipedia.org/wiki/ISO_8601

The ISO 8601 uses YYYY-MM-DD as representation (not yyyy or mm or dd).

things that have to be checked to achieve ISO 8601 conformance (maybe output is driven from settings outside DPL?)

• output variables, e.g. on Latest Modifications per user: invoked by addeditdate

things that have to be changed to achieve ISO 8601 conformance

• input fields on Template:Catlist

DynamicPageListSP_body.php

			    $wikitext2=	   "createdby          =? username"
			               	."\nmodifiedby         =? username"
			               	."\nlastmodifiedby     =? username"
			    			."\nfirstrevisionsince =? yyyy/mm/dd"
			               	."\nallrevisionssince  =? yyyy/mm/dd"
			               	."\nlastrevisionbefore =? yyyy/mm/dd"
			               	."\nallrevisionsbefore =? yyyy/mm/dd"
			               	."\nnotcreatedby       =? user"
			               	."\nnotmodifiedby      =? username"
			               	."\nnotlastmodifiedby  =? username"
			    		   	;

replace yyyy/mm/dd with YYYY-MM-DD (parsing already works, i.e. no dependencies)
