48x8 Matrix Clock

Other Hardware LEDs and Multiplexing

I have a working matrix scrolling program with the help of a forum member, and now need advice on how to have the time and date scroll twice then have only have the time displayed for, example 5 minutes then have the sequence repeat.
I am using 6xMax7219, DS1307 rtc, and UNO R3.
Program code is enclosed.

[/#include <SPI.h>
#include <Wire.h>
#include "RTClib.h"
#include <Adafruit_GFX.h>
#include <Max72xxPanel.h>

int pinCS = 10; // Attach CS to this pin, DIN to MOSI and CLK to SCK (cf http://arduino.cc/en/Reference/SPI )
int numberOfHorizontalDisplays = 5;
int numberOfVerticalDisplays = 1;


Max72xxPanel matrix = Max72xxPanel(pinCS, numberOfHorizontalDisplays, numberOfVerticalDisplays);
RTC_DS1307 rtc;

String tape ="99:99:99    99/99/9999";
int tape_length = 24;
int wait = 50; // In milliseconds

int spacer = 1;
int width = 5 + spacer; // The font width is 5 pixels
int i = 0;

void setup() {
  
  matrix.setIntensity(0); // Use a value between 0 and 15 for brightness
  #ifdef AVR
  Wire.begin();
#else
  Wire1.begin(); // Shield I2C pins connect to alt I2C bus on Arduino Due
#endif
  rtc.begin();
  
 if (! rtc.isrunning()) {
    matrix.print("RTC is NOT running!");
    // following line sets the RTC to the date & time this sketch was compiled
    rtc.adjust(DateTime(__DATE__, __TIME__));
  }
}

void loop() {

  DateTime now = rtc.now();
  // modify our tape to show the date and time
  
  tape[0] = '0' + ((now.hour())/10);  // I assume you want the time first
  tape[1] = '0' + ((now.hour())%10);
  tape[3] = '0' + ((now.minute())/10);
  tape[4] = '0' + ((now.minute())%10);
  tape[6] = '0' + ((now.second())/10);
  tape[7] = '0' + ((now.second())%10);
  
  tape[12] = '0' + ((now.day())/10); 
  tape[13] = '0' + ((now.day())%10);
  tape[15] = '0' + ((now.month())/10);
  tape[16] = '0' + ((now.month())%10);
  tape[18] = '0' + ((now.year())/1000);
  tape[19] = '0' + (((now.year())/100)%10);
  tape[20] = '0' + (((now.year())/10)%10);
  tape[21] = '0' + ((now.year())%10);
  
  for ( int i = 0 ; i < width * tape_length + matrix.width() - 1 - spacer; i++ ) {

    matrix.fillScreen(LOW);

    int letter = i / width;
    int x = (matrix.width() - 1) - i % width;
    int y = (matrix.height() - 8) / 2; // center the text vertically
    while ( x + width - spacer >= 0 && letter >= 0 ) {
      if ( letter < tape_length ) {
        
        matrix.drawChar(x, y, tape[letter], HIGH, LOW, 1);
      }
      
      letter--;
      x -= width;
         }
     matrix.write(); // Send bitmap to display
        
    delay(wait);    


  }
  
}
