timesyncd now uses ntp.nict.jp (stratum 1), with the JP pool and Ubuntu
as fallback, over whichever uplink holds the default route. Timezone
moves from Asia/Yakutsk to Asia/Tokyo: same offset, right place.
Records that the RTC loses time at power-off (the cold boot came up at
June 4 until NTP synced), and the planned chrony + gpsd setup once
GNSS has a fix.
