Ubuntu Core 16 - 如何持久地改變時區？

設定時區我嘗試如下：

auser@localhost:~$ sudo timedatectl
      Local time: Fri 2019-05-17 06:46:14 UTC
  Universal time: Fri 2019-05-17 06:46:14 UTC
        RTC time: Fri 2019-05-17 06:46:13
       Time zone: n/a (UTC, +0000)
 Network time on: yes
NTP synchronized: no
 RTC in local TZ: no
auser@localhost:~$ sudo timedatectl set-ntp 0
auser@localhost:~$ sudo timedatectl
      Local time: Fri 2019-05-17 06:46:34 UTC
  Universal time: Fri 2019-05-17 06:46:34 UTC
        RTC time: Fri 2019-05-17 06:46:33
       Time zone: n/a (UTC, +0000)
 Network time on: no
NTP synchronized: no
 RTC in local TZ: no
auser@localhost:~$ sudo timedatectl set-timezone Europe/Berlin
auser@localhost:~$ sudo timedatectl
      Local time: Fri 2019-05-17 08:46:56 CEST
  Universal time: Fri 2019-05-17 06:46:56 UTC
        RTC time: Fri 2019-05-17 06:46:55
       Time zone: Europe/Berlin (CEST, +0200)
 Network time on: no
NTP synchronized: no
 RTC in local TZ: no

一切看起來都很好，但然後重新啟動......

auser@localhost:~$ sudo reboot
auser@localhost:~$ sudo timedatectl
      Local time: Fri 2019-05-17 06:48:51 UTC
  Universal time: Fri 2019-05-17 06:48:51 UTC
        RTC time: Fri 2019-05-17 06:48:51
       Time zone: n/a (UTC, +0000)
 Network time on: yes
NTP synchronized: no
 RTC in local TZ: no

NTP 同步切換為 yes，本地時間和時區切換回 UTC。我怎麼能改變這些，使它在重新啟動後仍然存在？

為了安裝 snappy，請執行以下操作：

sudo apt install ubuntu-snappy-cli

為了讀取 ubuntu-core 的目前配置：

snappy config ubuntu-core

然後為了更新它：

CONFIG=/tmp/core_config

snappy config ubuntu-core > "$CONFIG"
sed -i 's/timezone: .*$/timezone: America\/Cordoba/' "$CONFIG"
sudo snappy config ubuntu-core "$CONFIG"

如前所述這裡。
