Might I be of assistance?

The computer outputs every minute, hour, month, etc. as a number, and it does not include a 0, as you might have noticed in hour().

You have to use the modulo and the floor functions to make your clock work properly.
I've already tested this code, and it should work.

1.     //time and date
2.     int mo = month();
   
3.     int d = day();
   
4.     int y = year();
   
5.     int mod = minute() % 10; //Displays the next unit number every minute
   
6.     int flo = floor(minute() / 10); //Displays the next tens number every ten minutes
   
7.     int h = hour();
   
8.      
   
9.      
   
10.     String timeDate = mo + "/" + d + "/" + y + " at " + h + ":" + flo + mod;
    
11.     println(timeDate);

- MenteCode.

or

1. 
       //time and date
       int mo = month();
       int d = day();
       int y = year();
       int m = minute();
       int h = hour();
        
       String timeDate = mo + "/" + d + "/" + y + " at " + h + ":" + nf(m,2);
       println(timeDate);

both excellent solutions. thank you. and it works now.
had to google "nf" and "modulo" (although i was more familiar with modulus, I remember from math classes), but learned something new.

Thank you to you both. And thank you for such a quick response!

This si now marked resolved.
