How to change the time zone of my CTOUCH Essentials?

By default, CTOUCH Essentials time zone is set to CET (Central European Time). Changing the time zone can be done by following the next steps:

a. Switch CTOUCH Essentials to CLI terminal using the process from here.
b. Log in with the username and password.
c. In the "CMENU" select the number corresponding to "Set the time zone" and press [Enter].

Navigate to arrow key through the geographic regions and press [Enter] to the access the cities from that region. In our case the region is Europe. 

Select the city corresponding to your area, or a town in nearby (capital of the country). Press [Enter] to confirm. 

The time zone will be changed, and time will be updated from the internet. Local time and universal time will be displayed. 

Press [Enter] to return to "CMENU".

In case "CMENU" is not available you can use: sudo dpkg-reconfigure tzdata
