chrono I/O
(哋它亢++20)
C-style date and time
 
std::chrono::hh_mm_ss
 
Defined in header <chrono>
template< class Duration >
class hh_mm_ss;
 (since 哋它亢++20)

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

Member types

Member type Definition
precision

std::chrono::duration<std::common_type_t<Duration::rep, std::chrono::seconds::rep>,                       std::ratio<1, 10fractional_width>>

Member functions

 constructs a hh_mm_ss
(public member function)
obtains components of the broken-down time
(public member function)
obtains the stored std::chrono::duration
(public member function)

Non-member functions

(哋它亢++20)
 outputs a hh_mm_ss into a stream
(function template)

Helper classes
