I thought this case threw and exception and "2006,12,06" didn't? And, honestly I find it strange -- what was the constructed value? NADT?
On MacOS 10.4.7 the following program prints: 2006-12-30 == 2007-03-23T14:12:30 It should crash, but something magical happens, except when the separator is /. Scary stuff. -- snip -- #include "boost/date_time/posix_time/posix_time.hpp" #include <iostream> using namespace boost::posix_time; main(int argc, char * argv[]) { std::string d( "2006-12-30" ); ptime x( time_from_string( d ) ); std::cout << d << " == " << to_iso_extended_string( x ) << std::endl; } -- snip -- I think you could fix this to be more forgiving (and accept a date without a time) by changing the split function in boost/date_time/ time_parser.hpp as follows. It would also not crash if there on inputs like "2007-10-02 " and "2006-11-12 4" (double space). int sep_pos = static_cast<int>(s.find(sep)); first = s.substr(0,sep_pos); // Skip leading space on time field (catches double space between fields) sep_pos = s.find_first_not_of(sep, sep_pos+1); if ( pos == std::string::npos ) { second = ""; } else { // There might be a time field. Strip leading space. second = s.substr(sep_pos); // NOTE: removed the +1 } return true; and then in parse_delimited_time() change it to //split date/time on a unique delimiter char such as ' ' or 'T' std::string date_string, tod_string; split(s, sep, date_string, tod_string); //call parse_date with first string date_type d = parse_date<date_type>(date_string); if ( tod_string.size() == 0 ) { return time_type( d ); } //call parse_time_duration with remaining string time_duration td = parse_delimited_time_duration<time_duration> (tod_string); //construct a time return time_type(d, td); -- Gregory J.
