Hi all,

I come across a bug in boost::posix_time::time_from_string();

try { ptime t1(time_from_string("2005-01-01")); cout << to_simple_string(t1) << endl; } catch (...) { cout << "exception thrown" << endl; }

The above code will strangely output: "2005-Mar-25 13:01:01"

time_from_string() will parse "2005-01-01 12", "2005-01-01 12:23" and "2005-01-01 12:23:33" correctly.

It will even parse "2005-01-01 34" to the next day and output "2005-Jan-02 10:00:00"

Does anyone have a fix for this bug? It should either parse correctly or it should throw an exception.

Thanks Michael _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users

You could parse the elements independently and check it yourself pretty trivially. time_duration td; date d; std::stringstream ss("2005-Jan-01 13:20:20"); ss >> d; ss >> td; if (td.hours() > 23 || td == not_a_date_time) {.... //parse failed.. Didn't compile the above, but should be close :-) from_string treats the second part as a time duration and isn't strict about limiting the input, so that's why it behaves as it does... Jeff
