Answer 1

No, but you can like this:

#include <iostream>
#include <ctime>

using namespace std;

string hh_mm_ss(time_t time) {
    tm *now = localtime(&time);
    string result;
    if (now->tm_hour < 10)
        result.push_back('0');
    result += to_string(now->tm_hour);
    result.push_back(':');
    if (now->tm_min < 10)
        result.push_back('0');
    result += to_string(now->tm_min);
    result.push_back(':');
    if (now->tm_sec < 10)
        result.push_back('0');
    result += to_string(now->tm_sec);
    return result;
}

int main() {
    time_t now = time(0);
    cout << hh_mm_ss(now);
    return 0;
}
