To set a time zone use the /etc/TZ file. Copy & paste the time zones from the table below into the file. In this example it's done with the echo command. 

echo "CET-1CEST-2,M3.5.0/02:00:00,M10.5.0/03:00:00" > /etc/TZ

NOTE: This sets the time zone for CET/CEST (Central European Time UTC+1 / Central European Summer Time UTC+2) and the start (5th week of March at 02:00) and end times (5th week of October at 03:00) of DST (Daylight Saving Time).
