26.10 Time zones [time.zone]

26.10.7 Class template zoned_­time [time.zone.zonedtime]

26.10.7.4 Non-member functions [time.zone.zonedtime.nonmembers]

template<class Duration1, class Duration2, class TimeZonePtr> bool operator==(const zoned_time<Duration1, TimeZonePtr>& x, const zoned_time<Duration2, TimeZonePtr>& y);
Returns: x.zone_­ == y.zone_­ && x.tp_­ == y.tp_­.
template<class Duration1, class Duration2, class TimeZonePtr> bool operator!=(const zoned_time<Duration1, TimeZonePtr>& x, const zoned_time<Duration2, TimeZonePtr>& y);
Returns: !(x == y).
template<class charT, class traits, class Duration, class TimeZonePtr> basic_ostream<charT, traits>& operator<<(basic_ostream<charT, traits>& os, const zoned_time<Duration, TimeZonePtr>& t);
Effects: Streams the value returned from t.get_­local_­time() to os using the format "%F %T %Z".
Returns: os.
template<class charT, class traits, class Duration, class TimeZonePtr> basic_ostream<charT, traits>& to_stream(basic_ostream<charT, traits>& os, const charT* fmt, const zoned_time<Duration, TimeZonePtr>& tp);
Effects: First obtains a sys_­info via tp.get_­info() which for exposition purposes will be referred to as info.
Then calls to_­stream(os, fmt, tp.get_­local_­time(), &info.abbrev, &info.offset).
Returns: os.
