In rend_consider_services_upload(), if (!service->next_upload_time), it sets

      /* The fixed lower bound of 30 seconds ensures that the descriptor
       * is stable before being published. See comment below. */
      service->next_upload_time =
        now + 30 + crypto_rand_int(2*rendpostperiod);

which sure seems to a casual reader like Tor initializes its first upload for the hidden service descriptor to be 30 seconds + a random fraction of twice the RendPostPeriod. So, an hour give or take.

But then right below that we check

        (service->desc_is_dirty &&
         service->desc_is_dirty < now-30)) {

and the service gets dirty whenever an intro point is established, which presumably happens soon after you start up your Tor.

We should verify that this behavior is what I think it is, and then we should at the least fix all the comments to be more accurate, and probably we should get rid of the "up to 2 hours" part of the code since it isn't working anyway.
