NAME¶

std::chrono::hh_mm_ss - std::chrono::hh_mm_ss

Synopsis¶

Defined in header <chrono>
template< class Duration > (since C++20)
class hh_mm_ss;

The class template hh_mm_ss splits a std::chrono::duration into a "broken down" time
such as hours:minutes:seconds, with the precision of the split determined by the
Duration template parameter. It is primarily a formatting tool.

Duration must be a specialization of std::chrono::duration, otherwise the program is
ill-formed.

Member constants¶

constexpr unsigned the smallest possible integer in the range [0, 18] such that
fractional_width precision (see below) will exactly represent the value of
[static] Duration{1}, or 6 if there's no such integer
(public static member constant)

Member types¶

Member type Definition
std::chrono::duration<std::common_type_t<Duration::rep,
precision std::chrono::seconds::rep>, std::ratio<1,
10^fractional_width>>

Member functions¶

constructor constructs a hh_mm_ss
(public member function)
is_negative
hours obtains components of the broken-down time
minutes (public member function)
seconds
subseconds
operator precision obtains the stored std::chrono::duration
to_duration (public member function)

Non-member functions¶

operator<< outputs a hh_mm_ss into a stream
(C++20) (function template)

Helper classes¶

std::formatter<std::chrono::hh_mm_ss> formatting support for hh_mm_ss
(C++20) (class template specialization)
