Discussion on %S format string expectations:
How many implementations interpret %S showing floating point/fractional seconds
Does SG14 members want to form an opinion on this, and if you care please send to Howard Hinnant
No question this is breaking backwards compatibility
Could also have casted the seconds to show only integer seconds
Specifically this C++20/23 code:
#include <chrono>
#include <format>
#include <iostream>
int
main()
{
using namespace std;
using namespace chrono;
auto tp = sys_days{August/30/2023} + 13h + 17min + 50s + 62ms;
cout << format(“{:%F %H:%M:%S}", tp) << '\n';
}
Outputs:
2023-08-30 13:17:50.062
And the LEWG voted to change the output to:
2023-08-30 13:17:50
(dropping the millisecond precision information in the time point).
