Re: [Help-tar] [PATCH] Add --clamp-mtime option

[Paul Eggert]

An option along these lines sounds like it would be useful, thanks.  But I have 
some confusions and/or problems with the suggestion.

First, the patch doesn't alter the documentation, which is typically the hardest 
part of any change like this.  The documentation should give an example of how 
the new option would be useful.

Second, I'm having trouble seeing how to use the option (and this is probably 
because of the first item...).  How does the maintainer keep track of a clamped 
mtime?  Isn't that a hassle to maintain?  Can't 'tar' do this for you, instead 
of your having to do it?
