    Does C++ have any standard implementation for time/date?

    I'm just looking for a simpler method to get the time and date than the ctime class provides. I want one where it's a little easier to format. I was at first trying to figure out the strftime but ended up using the

    Code:
    Date::Date()
    {
        time_t rawtime;
        rawtime = time(&rawtime);
        string junk;
    
        istringstream i (ctime(&rawtime));
        i >> junk >> month >> day >> junk >> year;
    }
    I don't know what it means but I ended up with some junk values. I easily threw away, but is there a more standard library that provides similar functions.

    Code:
    #include <iostream>
    
    using namespace std;
    
    int main()
    {
    cout << "The time is: " << __TIME__ << endl;
    cout << "The date is: " << __DATE__ << endl;
    
    return 0;
    }

    Not really, since those aren't defined by the standard and may not be implemented on another compiler.

    The standard way is the one defined by the ctime header and the one you were trying to use. I suggest you keep at it. After a while you'll get used.

    Except __DATE__ is constant for the time the program was compiled.
    Run it tomorrow, and it will still be the same.

    You mean like gmtime() and localtime() which return a 'struct tm' full of time components.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
