Yeah that's a bug...still. I'll look at it. It may be doubtful for this
release, but see below -- you have more capable options now....

Yes, but the new facets are much better than 1.32. They now support 'format
string' based input and output. Here's how I'd implement your parsing problem
for narrow and wide streams:
using namespace boost::gregorian;
using namespace boost::posix_time;
using namespace std;
time_input_facet* tf = new time_input_facet();
//below sets: %Y%m%dT%H%M%S%F for format.
ss >> pt3;
cout << "pt3: " << pt3 << endl;
//this time we'll set the format
wtime_input_facet* wtif = new wtime_input_facet(L"%Y%m%dT%H%M%S%F");
// wtif->set_iso_format(); <-- this works too...
wss >> pt4;
wtime_facet* wtf = new wtime_facet();
wcout << "pt4: " << pt4 << endl;
pt3: 2002-Oct-17 23:12:17.123450
You can read more in the 1.33 docs at:
or download in pdf form:
ps: Make sure you update your CVS -- I just fixed a bug that impacted input
