Defined in header <chrono>
template <class CharT, class Traits, class Duration, class TimeZonePtr>

std::basic_ostream<CharT, Traits>&
operator<<( std::basic_ostream<CharT, Traits>& os,

            const std::chrono::zoned_time<Duration, TimeZonePtr>& tp );
(since C++20)

Outputs tp to the stream os, as if by std::format(os.getloc(), fmt, tp), where fmt is "{:L%F %T %Z}" if CharT is char, or L"{:L%F %T %Z}" if CharT is wchar_t.

Parameters

os - output stream
tp - zoned_time to output

Return value

os.
