Timezone (%Q) is ignored in time_input_facet / local_time_input_facet

[Maurice Gilden <MauriceG@…>]

I'm trying to parse an extended ISO 8601 date-time string to ptime or local_time using the following code:

	boost::local_time::wlocal_time_input_facet *inputFacet = new boost::local_time::wlocal_time_input_facet();
	inputFacet->set_iso_extended_format();
	std::wstringstream ss;
	ss.imbue(std::locale(ss.getloc(), inputFacet));
	ss.str(inputString);
	boost::local_time::local_date_time time(boost::local_time::not_a_date_time);
	ss >> time;

This works for "2013-08-20T17:14:21Z" or "2013-08-20T17:14:21", however it doesn't work as soon as I add a timezone to it, e.g. "2013-08-20T19:14:21+02" or "2013-08-20T19:14:21+02:00". As far as I can tell the error is because the timezone (%Q) is completely ignored in time_facet.hpp.
