=====strftime=====
Syntax:

<code>
    #include <ctime>
    size_t strftime( char *str, size_t maxsize, const char *fmt, struct tm *time );
</code>

The function strftime() formats date and time information from time to a format specified by fmt, then stores the result in str (up to maxsize characters).

Certain codes may be used in fmt to specify different types of time:
