David found his client unable to connect to his service. Apparently, they compute different hsdir indices, since it was 12:20UTC (non-overlap period) and the live consensus had valid-after at 11:00UTC (overlap period). Apparently something got confused. Theory: We use `time(NULL)` as the time in `node_set_hsdir_index()` whereas we use the live consensus `valid-after` in `rotate_all_descriptors()`. This can cause desynch within the same tor instance. We should probably use the live consensus `valid-after` in all cases to have a common point of reference, and avoid problems with clock skews.
