1. What is true about the file /etc/localtime?

   • After changing this file, newtzconfig has to be run to make the changes effective.
   • It is either a symlink to or a copy of a timezone information file such as /usr/share/zoneinfo/Europe/Berlin.

9. FILL BLANK

   Which command must be run after adding a new email alias to the configuration in order to make this change effective? (Specify the command without any path but including all required parameters.)

12. Why is the correct configuration of a system’s time zone important?

    • Because the timezone is included in checksum calculations and timezone changes invalidate existing checksums.
    • Because the time zone is saved as part of the modification times of files and cannot be changed after a file is created.
    • Because the environment variables LANG and LC_MESSAGES are, by default, set according to the time zone.
    • Because NTP chooses servers nearby based on the configured time zone.
    • Because the conversion of Unix timestamps to local time relies on the time zone configuration.
