Defined in header
<chrono>
template< class CharT, class Traits, class Duration >
(since C++20)
std::basic_ostream <CharT, Traits>&
operator<<( std::basic_ostream <CharT, Traits>& os,
Outputs t into the stream os.
Equivalent to return os << std::format (os.getloc(), STATICALLY_WIDEN<CharT>("{:L%T}"), hms); where STATICALLY_WIDEN<CharT>("{:L%T}") is "{:L%T}" if CharT is char, and L"{:L%T}" if CharT is wchar_t.
[edit] Parameters
os
-
the output stream
t
-
the time of day to be output
[edit] Return value
