We need a way to have time/date ajust for our timezone in order to have right ETA in the UI.
Temporary solution:
# SSH to your cnc using user and password.
sudo -i # enter same password
############
# MOUNT OS RW
############
sudo mount -o remount,rw /boot # makes the file system writable
sudo apt-mark hold hostapd # prevent update to hostapd
############
# UPDATE OS
############
sudo apt-get update -y # update
sudo apt-get upgrade -y # upgrade
############
# SETUP NTP
############
# REF https://www.digitalocean.com/community/tutorials/how-to-set-up-timezone-and-ntp-synchronization-on-ubuntu-14-04-quickstart
TZ='America/Toronto'; export TZ # run this and also add it to line 1 of .profile
sudo nano .profile # save it by pressing CTRL + X then Y followed by ENTER.
sudo timedatectl set-timezone America/Toronto # adjust timezone to your region (see REF above)
sudo apt-get update -y # update
sudo apt-get install ntp # install ntp
############
# MOUNT OS RO
############
sudo mount -o remount,ro /boot # makes the file system read-only
############
# RESTART SYSTEM
############
sudo reboot
