From the docs I see:

"date(greg_year, greg_month, greg_day) Construct from parts of date. Throws bad_year, bad_day_of_month, or bad_day_month (derivatives of std::out_of_range) if the year, month or day are out of range." In my use case, I know for sure that the year, month and date are all in the valid range of values, so all the validity checks done by the library become redundant. Is it possible to somehow bypass those checks?
