File creation time should never be used for anything other than relative staleness checks.
If it's a meaningful part of the file content, it had better be part of the file content. :)
You're absolutely right! I updated this posts title to account for this more general truth. Your comment can stay how it is, it still makes sense :-D
Just curious: What do you consider a 'staleness check'? (when would you do that)? Thanks!
Let's say that one file is produced from another.
It is never incorrect to regenerate it, but unnecessary unless the other file has since been modified.
Or say that the file is sufficiently up to date not to regenerate if it was modified less than some time ago.
I see, thanks!
