Comment:

 Is the place to do this change `check_descriptor_bandwidth_changed`
 (https://gitweb.torproject.org/tor.git/tree/src/or/router.c#n2629)?

 If i've the line
 https://gitweb.torproject.org/tor.git/tree/src/or/router.c#n2643 as:
 `if (get_uptime() < 60*60*24 && last_changed+MAX_BANDWIDTH_CHANGE_FREQ <
 now || !prev)`, then the descriptor would still be uploaded when there is
 not `prev`.

 Should instead i do `get_uptime() > 60*60*24 return;` at the beginning of
 the function so that there are not any further checks when the relay is up
 for more than 1 day?
