Merge the spoken-plan zone fix (#259)

FormatRU printed the raw instant, so it read the plan's hours in
whatever zone the value carried. The live case is the rest-of-day path:
'что дальше?' rebuilds a morning.Plan off ipc.DayPlan, and nothing there
had put the instants in the asking clock's frame. It is the only
producer of a Plan that skips BuildPlan, which has localized events and
reminders since it was written.

formatTime, the answer to 'когда я это сделал?', had the same shape on a
fact's Ts, which is UTC out of the store.

Each test builds its instants three hours off the machine's zone, so
they fail under TZ=UTC as well.

(V-614)
