C-style date and time

template < class CharT, class Traits, class Duration > std:: basic_ostream < CharT, Traits > & operator << ( std:: basic_ostream < CharT, Traits > & os, const std:: chrono :: local_time < Duration > & tp ) ;		(C++20以降)

tp をストリーム os に出力します。これは os << std:: chrono :: sys_time < Duration > ( tp. time_since_epoch ( ) ) ; によって行われるかのように動作します。
