RTC and Interval Timing

Well I finally got it working. Now I just hope you might be able to make sense of this to me. It was certainly the fact that I didn't have the pinMode set to output but here is where I'm confused.

When I try to set up my relay pins as constants like so

#include <DS3232RTC.h>
#include <Time.h>
#include <Wire.h>



void setup() {
 
pinMode(22, OUTPUT);
pinMode(23, OUTPUT);
pinMode(24, OUTPUT);
pinMode(25, OUTPUT);

  
 Serial.begin(9600);
 setTime(10,1,0,9,14,16);
}
 
void loop()
{
 fanTimer(); //add call to function
 digitalClockDisplay();
 delay(1000);
}
 
void digitalClockDisplay(){
 // digital clock display of the time
 Serial.print(hour());
 printDigits(minute());
 printDigits(second());
 Serial.print(" ");
 Serial.print(day());
 Serial.print(" ");
 Serial.print(month());
 Serial.print(" ");
 Serial.print(year());
 Serial.print(" ");
 Serial.print((char)223);
 Serial.print('C');
 Serial.println();
}
 
void printDigits(int digits){
 // utility function for digital clock display: prints preceding colon and leading 0
 Serial.print(":");
 if(digits < 10)
 Serial.print('0');
 Serial.print(digits);
}

void fanTimer()
  {
if ( minute() >= 0 && minute() < 5)
{
  digitalWrite ( 22, HIGH );
}
else 
{
 digitalWrite ( 22, LOW );
}
}

I get the following error

sketch_sep15a.ino:6:1: error: expected unqualified-id before numeric constant
sketch_sep15a.ino:6:1: error: expected ',' or ';' before 'const'
Error compiling.

but if I remove the constants and express the program like this

#include <DS3232RTC.h>
#include <Time.h>
#include <Wire.h>



void setup() {
 
pinMode(22, OUTPUT);
pinMode(23, OUTPUT);
pinMode(24, OUTPUT);
pinMode(25, OUTPUT);

  
 Serial.begin(9600);
 setTime(10,1,0,9,14,16);
}
 
void loop()
{
 fanTimer(); //add call to function
 digitalClockDisplay();
 delay(1000);
}
 
void digitalClockDisplay(){
 // digital clock display of the time
 Serial.print(hour());
 printDigits(minute());
 printDigits(second());
 Serial.print(" ");
 Serial.print(day());
 Serial.print(" ");
 Serial.print(month());
 Serial.print(" ");
 Serial.print(year());
 Serial.print(" ");
 Serial.print((char)223);
 Serial.print('C');
 Serial.println();
}
 
void printDigits(int digits){
 // utility function for digital clock display: prints preceding colon and leading 0
 Serial.print(":");
 if(digits < 10)
 Serial.print('0');
 Serial.print(digits);
}

void fanTimer()
  {
if ( minute() >= 0 && minute() < 5)
{
  digitalWrite ( 22, HIGH );
}
else 
{
 digitalWrite ( 22, LOW );
}
}

It works like it should. any ideas?
