calendar.h ~ calendar ~ duration_type

struct duration_type;

Description

Defines structure to store human-readable duration representation.

The helper function calendar::make_duration permits to easily initialize a duration_type structure by calculating default values for other members. If one member is initialized with a value outside of its predefined range, the program is ill-formed and might result in undefined behaviour.

Member variables

Name	Value	Description
year	integer from 0 to 292471208	Year
month	integer from 0 to 11	Month in a year
week	integer from 0 to 4	Week in a month
day	integer from 0 to 6	Day in a week
hour	integer from 0 to 23	Hour
min	integer from 0 to 59	Minute
sec	integer from 0 to 59	Second
milli	integer from 0 to 999	Millisecond

Examples

#include <iostream>
#include <JLC/JLC.h>
using namespace JLC;
using typename calendar::duration_type;

int main(){
    constexpr duration_type duration = calendar::make_duration(0,0,123);
    std::cout << "123 weeks = " << duration.year << " years";
    std::cout << " + " << duration.month << " months";
    std::cout << " + " << duration.week << " weeks";
    std::cout << " + " << duration.day << " days" << std::endl;
}

123 weeks = 2 years + 4 months + 1 weeks + 0 days
