unsigned boost::chrono::detail::days_before_years ( int32_t  y )

inline

from_ymd could be made more efficient by using a table day_count_table indexed by the y%400.

This table could contain the day_count by*365 + by/4 - by/100 + by/400

from_ymd = (by/400)*days_by_400_years+day_count_table[by%400] + days_in_year_before[is_leap_table[by%400]][m-1] + d;
