One Revpi Connect is logging sensordata on a ship.
It is in a remote part of the ship and not connected to a network.
It has a WiFi USB and acts as an ap for servicepeople to connect and download the logs.
All of a sudden, sometime during the summer (probably around end of July) the system time was set back to some time in April.
So two questions :
a) what could possibly be the reason ?
b) what is the recommended way to permanently change system time ?
We have been doing :
sudo timedatectl set-ntp false
sudo timedatectl set-time '2019-07-09 13:01:00'
Any tips appreciated...
