Comment:

 From the log you sent me, I noticed that the voting period are
 synchronized. Is it possible we are in a timezone issue situation here
 because if I take your local timezone and convert it to UTC, the logs do
 add up:

 {{{
 Jan 07 09:48:14.984 [info] sr_state_update: SR: State prepared for
 upcoming voting period (2018-01-06 23:00:00). Upcoming phase is reveal
 (counters: 0 commit & 1 reveal rounds).
 }}}

 09:48 Australia Time -> 22:48 UTC so the upcoming voting period is indeed
 23:00 UTC.
