+ * [shogi-server] shogi_server/time_clock.rb:
+ - A time consumed could be -1.
+ * The start time of a move is captured after sending a move to a
+ player of the next turn at the end of the giant lock
+ * The end time of the move is captured at the exact time when the
+ server receives it before the giant lock
+ Therefore, end_time < start_time is possible when a player returns a
+ move instantly.
+ Thanks to Tomoyuki Kaneko for reporting this issue.
