Adjustment
The LINUX real time clock always shows UTC time, while the built-in
clock in AutroMaster shows the local time with one or two hours offset
from the UTC time.
To configure automatic change of summer and winter time for the
AutroMaster clock, proceed as follows:
 Use the editor to create a file named .crontab in the /home/spefun.
 # Summer time adjustment
0 1 * 3,10 0 /usr/local/amtimeadjust
 Save the file.
 Run the command crontab .crontab
 Open the file “grafikkstart”-file in the editor.
 Add the line amtimeadjust at the end of the file.
 Save the file.
