After a talk with stgraber, this is a due to the fact that the Ubuntu LXC I build are using a pre-generated image which uses UTC by default.
If you want to change the time on Xenial, in my case date command or other technic didn't have positive impact. The only thing that work so far is to unlink /etc/localtime and link it to the desired zone. example : #ls -altr /etc/localtime lrwxrwxrwx 1 root root 27 Oct 12 15:59 /etc/localtime -> /usr/share/zoneinfo/Etc/UTC # unlink /etc/localtime # ls -altr /etc/localtime ls: cannot access '/etc/localtime': No such file or directory # ln -s /usr/share/zoneinfo/America/Toronto /etc/localtime # ls -altr /etc/localtime lrwxrwxrwx 1 root root 35 Oct 12 12:05 /etc/localtime -> /usr/share/zoneinfo/America/Toronto Eric -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1632766 Title: time in lxc ubuntu template Status in lxc package in Ubuntu: Invalid Bug description: With regard to github bug : --- adjust timezone to the host at creation time #47 https://github.com/lxc/lxc/issues/47 --- I still can reproduce the problem on different HW running Xenial with the LXC ubuntu image Trusty and Xenial. * Bare metal (xenial) $ date Wed Oct 12 11:27:55 EDT 2016 LXC (Trusty) $ sudo lxc-attach -n trusty root@trusty:/# date Wed Oct 12 15:28:10 UTC 2016 * Bare metal #2 (xenial) $ date Wed Oct 12 11:28:57 EDT 2016 LXC (Xenial) $ lxc-attach -n xenial $ date Wed Oct 12 15:29:32 UTC 2016 Note, that using the debian template everything works fine : Bare metal #1 (xenial) $ date Wed Oct 12 11:30:40 EDT 2016 $ lxc-attach -n debian8 $ date Wed Oct 12 11:30:45 EDT 2016 However debian and ubuntu got the same piece of code : # lxc-debian.in 149 # set initial timezone as on host 150 if [ -f /etc/timezone ]; then 151 cat /etc/timezone > "$rootfs/etc/timezone" 152 chroot "$rootfs" dpkg-reconfigure -f noninteractive tzdata 153 elif [ -f /etc/sysconfig/clock ]; then 154 . /etc/sysconfig/clock 155 echo "$ZONE" > "$rootfs/etc/timezone" 156 chroot "$rootfs" dpkg-reconfigure -f noninteractive tzdata 157 else 158 echo "Timezone in container is not configured.
