When we introduced legacy/trac#25552, we started OPE encrypting the time diff since the start of the SRV run. We also have some logic on which SRV period we should use to calculate the time diff: ``` if (is_current) { srv_start = sr_state_get_start_time_of_previous_protocol_run(); } else { srv_start = sr_state_get_start_time_of_current_protocol_run(); } ``` There is a bug here, because when we cross from the 23:00 consensus to the 01:00 consensus, the start of the SRV protocol changes and screws up the revision counter monotonicity. This causes one descriptor batch upload to fail.
