Why do I receive a 'Can't open file' error when I have a ':' character in my file name in MATLAB 7.4 (R2007a)?

When I execute the following commands:

logname = sprintf('Log-%s',datestr(now,31)) 

diary(logname)

I receive the following result:

 ??? Error using ==> diary

 Log-2007-03-03 22:27:09: Can't open file.

I would like an error message telling me that I cannot use a : character in the file name.

The ability to have a colon ':' in a file name is not available in MATLAB.

There are no workarounds.
