How do I avoid getting a "std::exception" Exception message is: could not convert calendar time to local time when I use dir and there is a file with a future date?

I get the error "std::exception" Exception message is: could not convert calendar time to local time when I use the dir command on a directory in which there is a file on disk with a future date (e.g. 27 July 2079). The file is a JPG image from a digital camera whose date had not been set correctly. I don't want to have to manually search all folders and files and change manually change the date.

I can reproduce the issue and will be reporting the bug to mathworks shortly.

If your're on Windows, you can use .Net to list the directory content with:

files = cell(System.IO.Directory.GetFiles(foldername));

Otherwise, you can always use:

files = system('dir')

and do a lot of parsing

[Guillaume]

To reproduce the issue, on Windows:

fname = fullfile(pwd, 'demomtime.txt');
f = System.IO.File.Create(fname);
f.Close
System.IO.File.SetLastWriteTime(fname, System.DateTime(2079, 7, 27)); %set modification time to 27 July 2079
s = dir;

I've now had confirmation from Mathworks that this is a bug. It should appear in their bug database at some point.

Thanks Guillaume for your help. Your suggestions work. I've just discovered that the imfinfo command also gives the same error, presumably because the bug is in some underlying function. Mike

Hello,

I've got the same question when copying a matlab m file to another computer.

It is easy to solve: open the file with any windows application, ex. note, and save it. Then the "last modified date" becomes the current date and you can then open it with Matlab.
