Answer 1

#include <iostream>
#include <chrono>

std::string epochDateTimeToString(std::chrono::system_clock::time_point &t) {
    std::time_t time = std::chrono::system_clock::to_time_t(t);
    
    std::string s = std::ctime(&time);

    return s;
}

int main() {
    std::chrono::system_clock::time_point epoch_time;
    
    std::cout << epochDateTimeToString(epoch_time);

    return 0;
