Correct Time Zone
I noticed on my Apple TV that the time-zone was wrong. Upon further examination it was set to use the Europe/Rome time zone
ls -lah /etc/localtime lrwxr-xr-x 1 root wheel 33B Apr 8 22:53 /etc/localtime -> /usr/share/zoneinfo/Europe/Rome
To correct to my local time zone (Europe/London) I ran:
sudo ln -s /usr/share/zoneinfo/Europe/London /etc/localtime
Alternatively, copy SystemPreferences.app from an Intel Mac and use the Date/Time preferences pane to set your time-zone
