[tor-relays] default value (after reboot ) of controller.get_server_descriptor.uptime changed ?

I do wonder, why a python script [1], lines 22 and 113, nowadays returns "00:00:00" for the uptime of my exit relay, when the system was rebooted, whereas in former times '00:01:01' (= 61 sec) was returned. FWIW the only local change before reboot here was to switch from Gentoo hardened kernel 4.0.6 to 4.0.6-r1.
