Comment (by nickm):

 Hi!  I think case 1 above is impossible, since do_hup() is a signal
 handler, and the signal handlers aren't even installed until later in
 tor_main() than first update_approx_time() call.  I agree that case 2 is
 unlikely, given OS behavior.

 Based on our earlier discussion with jvoisin, we found that the relay
 "jafar" had gotten an unexpected crash.  Also, it's running on an
 ODROID-C1.  Those together make it seem likelier to me that your case 4
 ("The OS believes it's 1970") is the likeliest explanation.
