Time difference between two sets of times in hrs mins and seconds.. GUI if possible

Hi im new to MATLAB and trying to setup a GUI to calculate the time difference between two sets of times. Eg: 10:00:00 and 11:01:00

Difference would be 1 hr 1min and 0 seconds..

thanks in advance

Hi Sharon, I have written a code for this a long time ago. Hope this helps..

close all

 % Prompt to enter the time using GUI
  prompt ={'Enter Start time and  End time:'};
  dlg_title = 'Time difference calculator';
  num_lines=1;
  def={'0 0 0 1 1 1'};
  str1 = inputdlg(prompt,dlg_title,num_lines,def);
  time1=str2num(str1{1});

 % get the times
 time1hr=time1(1);
 time1min=time1(2);
 time1sec=time1(3);

 time2hr=time1(4);
 time2min=time1(5);
 time2sec=time1(6);

 time1out=(time1hr*60*60)+(time1min*60)+time1sec;
 time2out=(time2hr*60*60)+(time2min*60)+time2sec;

 % actual calculation
 diffInSec=time2out-time1out
 diffInMin=diffInSec/60

 if diffInMin >60
    Hrs=(diffInMin/60)-mod(diffInMin/60,1)
    minutes=diffInMin-(Hrs*60)-mod(diffInMin,1)
    seconds=diffInSec-(Hrs*60*60)-(minutes*60)
 else
    afterdecimal=mod(diffInMin,1);

    minutes=diffInMin-afterdecimal
    seconds=diffInSec-(minutes*60)

 end

Thanks for the quick reply. This was what I needed. Wasn't sure how much time a reply would take.

So start by opening GUIDE

guide %at the command line

Then draw the GUI so that it has edit boxes to enter times, static boxes to give directions, and a push button to press to give you the times. After that, write the functions to do the work. Or write the functions to do the work first and then add them to a GUI. Ask specific detailed MATLAB questions here when you get stuck.

Thanks. Will try the guide from the command as well

>> duration("11:01:00")-duration("10:00:00")
ans = 
duration
01:01:00
>> string(duration("11:01:00")-duration("10:00:00"))
ans = 
"01:01:00"
>> [h, m, s]=hms(duration("11:01:00")-duration("10:00:00"))
h =
     1
m =
     1
s =
     0
>> d = duration(h,m,s)
d = 
  duration
   01:01:00

These work even if you include the dates.

See https://se.mathworks.com/help/matlab/ref/calendarduration.split.html for

   [m,d,t] = split(T,{'months','days','time'})
