Are there instances where modification time is not supposed to change?

Various backup tools have had such things from time to time. But
personally, it would never occur to me that a tool would have such a
setting TURNED ON(!) by default. Ouch!

For another fun misfeature, I have taken to using the -n option with
gzip all the time recently. It turns out that gzip has started writing
a timestamp into the compressed output. This means you can compress two
files with identical content and get different .gz files :-( Caused a
lot of trouble for my hard-link tree backup setups.
