With strftime a single digit 12-hour hour can be formatted to not have a leading zero using %-I. This seems to not be possible with fmt::format.
#include <iostream>
#include <fmt/chrono.h>
int main() {
std::cout << "%-I:%M using strftime:" << std::endl;
std::time_t t_ = std::time(nullptr);
char mbstr[100];
if (std::strftime(mbstr, sizeof(mbstr), "%-I:%M", std::localtime(&t_))) {
std::cout << mbstr << std::endl;
}
std::cout << "%-I:%M using fmt::format:" << std::endl;
const auto t = std::chrono::system_clock::to_time_t(std::chrono::system_clock::now());
const auto time_str = fmt::format("{:%-I:%M}", fmt::localtime(t));
// terminate called after throwing an instance of 'fmt::v8::format_error'
// what(): invalid format
std::cout << time_str << std::endl;
return 0;
}
There are probably more instances where strftime parity is not quite met. It would great if it was, or if any user error could be pointed out :)
