simple_custom_timestamp.cpp

#include <ctime>
#include <bits/stdc++.h>

std::string getTimestamp(char* format) {
    std::time_t epoch_time = std::time(nullptr);
    std::stringstream stream;
    stream << std::put_time( std::localtime(&epoch_time), format );
    return stream.str();
}

int main(int argc, char *argv[]){
    std::cout << getTimestamp( (char*) "Current timestamp is: %Y-%m-%d %H:%M:%S" );
