Comment 2 for bug 1734967

I'll set this bug as affecting php package, since this tzdata change is modifying the behaviour of php timezone.

## REPRODUCER ##

ubuntu@trusty:~# sudo ln -sf /usr/share/zoneinfo/America/Godthab /etc/localtime

ubuntu@trusty:~# reboot

ubuntu@trusty:~# ls -altr /etc/localtime
lrwxrwxrwx 1 root root 35 Nov 29 10:34 /etc/localtime -> /usr/share/zoneinfo/America/Godthab

ubuntu@trusty:~# date
Wed Nov 29 11:01:30 -03 2017

ubuntu@trusty:~# php /tmp/php_tz.php
America/Sao_Paulo

#/tmp/php_tz.php :

<?php
$script_tz = date_default_timezone_get();

echo $script_tz;
?>
