12910	boost::date_time::time_input_facet throws when using %j alone	Laurent Dupuy <pizzafroide@…>	James E. King, III	"With a format such as `""%j-%H:%M:%S""`, `boost::date_time::time_input_facet` throws an error because when using `""%j""`, the computation of the date is:
{{{#!cpp
date_type d(not_a_date_time);
if (day_of_year > 0) {
  d = date_type(static_cast<unsigned short>(t_year-1),12,31) + date_duration_type(day_of_year);
}
}}}
And `t_year` is 1400! I am in a situation where I need to parse such a date/time though...

Instead couldn't the computation be as follows?
{{{#!cpp
date_type d(not_a_date_time);
if (day_of_year > 0) {
  d = date_type(static_cast<unsigned short>(t_year), 1, 1) + date_duration_type(day_of_year - 1);
}
}}}
If so, the result of parsing `""263-08:09:10""` would be `""1400-Sep-20 08:09:10 UTC""`. (And I'm good with that.)
