 Replying to [comment:28 dgoulet]:
 > Shouldn't we put it to info log? Not sure this is something worth
 telling the operator when it happens because the operator can't do
 anything or at best sync its clock?...

 I'm a bit nervous about quieting it -- it seems there should be a real bug
 here, right? My relay has lines like
 {{{
 Dec 21 14:19:54.371 [notice] Channel padding timeout scheduled 617944ms in
 the past.
 Dec 22 16:22:23.034 [notice] Channel padding timeout scheduled 209517ms in
 the past.
 Dec 28 14:18:18.271 [notice] Channel padding timeout scheduled 165914ms in

 }}}
 and I'm quite sure it isn't just freezing for 10+ minutes at a time.

 How is Tor setting its timeouts for so far in the past?
