Details:

The following loop will demonstrate the bug. At the end of the loop, the file
will correctly have A=5 saved but the file modified date/time displayed in
Windows will be the first minute that the file was created, not the last time
it was updated. 

 
for ii = 1:5 
  A = ii; 
  save('TestFile.mat','A') 
  pause(60)
end


This might be more of an issue with Windows than Octave, but it does work as
expected in MATLAB. This minor issue gave me a mini heart attack when I
noticed that code that I had running for a while apparently wasn’t updating
the save file. Thanks!
