Setting the time on a RTC

Well first of all i sorry for my grammar

Anyways.
I am using a ChronoDot from macetech. Its pretty much a ds3231.
I was able to get the time to show on the serial monitor using the time library
http://www.arduino.cc/playground/Code/Time

anyways. I am confuse on how to use the settime thingy

 setTime(hr,min,sec,day,month,yr); // another way to set the time

Anyways. in this segment of my program i am trying to add one minute to the current time when i press button 6

  buttonState6 = digitalRead(button6);
  if(buttonState6 == HIGH)
  {
    int minplus = minute();
    setTime(hour(),minplus++,second(),day(),month(),year());
  }

Nothing seems to work when i try this.
Also i change all the "int ###" to "###()" because the first thing didn't work.

Anyways... Thanks for any help

int hr = hour();
int min = minute();
int sec = second();

Then, you can use hr, min, sec in the call to setTime.

Nothing seems to work when i try this.

We'd need to see more of your code. Are you reading the new time? Are you displaying the new time?

If you want to set a new time by adding or subtracting a value from the current time, you can use the adjustTime function. This function takes the number of seconds and adjusts the current time. A positive value adds and a negative number subtracts the given number of seconds to set the current time.

This, from the library documentation:
adjustTime(adjustment); // adjust system time by adding the adjustment value
