You haven't answered my question.
If it's neccesary to change or replayce the file, and/or if it's possible to force to replace the file are two different things. I want the answer to the later one.
Besides, what you said is not correct. I've change only the mtime of file, but it was not replaced. Only I do any change in the file, such as add a space, this file is replaced. This means, only the md5 changed then the file will be replaced.
