To slightly expand on Eric's answer: a re-ordering of patches during a push, pull, or record does /not/ change the hash (which is made of author, date, and patch name plus some random number) of any any existing patch, nor does it change the date of the patch. It /may/ change the content of a patch so that it 'does the same thing' in its new context (whatever that means precisely, I am not an expert on patch theory). However, as Eric pointed out there are some 'destructive' commands, that change or delete patches (includinhgg their identity); these should not be allowed in a shared repo anyway.
