loop for clock each step is 20 min how to code this

Hi everyone,

i have a problem coding for "clock", that means that the code should only go up to 60 min. and then start over. I know that I have to supply this with an "if-statement, that says if the minutes > 60 then it has to add 1 to the hour and subtract 60 from the minutes.. But how do i code this? How to define i as the hour and j as minutes?

My code so far:

   for i = 13:0.2:20; 
       j = 13.16:0.2:20.16;
       fprintf('The Train from London %.2f arrives in Campden at %.2f\n', i, j);
   end

Output should look like this:

The Train from london 13.00 arrives in Campden at 13.16 
The Train from london 13.20 arrives in Campden at 13.36 
The Train from london 13.20 arrives in Campden at 13.56 
. . .
The Train from london 20.00 arrives in Campden at 20.16

The train leaves every 20 min and takes 16 min to arrive.

Edit

a=datenum('13:00','HH:MM')
b=datenum('20:00','HH:MM')
jj=a:(1/(24*3)):b
date1=datestr(jj,'HH:MM')
date2=datestr(jj+1/(90),'HH:MM')
for k=1:size(date1,1)
  fprintf('The Train from London %s arrives in Campden at %s\n', date1(k,:),date2(k,:));
end

Thanks! Can l also do it by separate hour and minute in different variables and then supply with an "if-statement, that says if the minutes > 60 then it has to add 1 to the hour and subtract 60 from the minutes.. Or is the other way easier?
