Then what you need is the tm structure and a function called local time.
There is a simple example on this page.
http://www.cplusplus.com/reference/clibrary/ctime/localtime.html
Note they just print the full time in this string but if you look in your
time.h file you will find all the tm_day tm_month tm_year fields that you
can use in the structure tm if you still have trouble just drop me a line
and I will create another simple program.
A hint is use the tm structure that they pass to the asctime function but
use it like bla.tm_day etc.

I have read it, but mktime and the others will not work as they make the
entire string and all I am trying to get out of the deal is the minutes, not
the entire thing. I could make minutes out of the seconds like you did, but
that would be a very large amount of minutes that I could not get as being
either on the hour or 15, 30, or 45 minutes after the hour. Similar with
the hour itself; I could not say which hour it is. Is there a way of
getting the minutes out of the tm object, defined in the object definition
as tm_min?
Have a great day,
Alex
