** Description changed:
- After release upgrading from 12.04 to 12.10, I remarked that the graphs
- are not updated anymore and the modify date of the files in
- /var/lib/cacti/rra was a timestamp before the upgrade.
+ An upstream change in PHP requires php.ini to have the timezone set in
+ there, instead of PHP using the system timezone as one might expect.
- I had many lines in /var/log/cacti/poller-error.log like this one:
- PHP Warning: date(): It is not safe to rely on the system's timezone
settings. You are *required* to use the date.timezone setting or the
date_default_timezone_set() function. In case you used any of those methods and
you are still getting this warning, you most likely misspelled the timezone
identifier. We selected the timezone 'UTC' for now, but please set
date.timezone to select your timezone. in
/usr/share/cacti/site/lib/functions.php on line 486
+ This is new in PHP 5.4.
- According to the FAQ page of cacti, I adjusted the php.ini in /etc/php5/cli
and /etc/php5/apache2:
- http://docs.cacti.net/faq#time_zone_warning
+ Not affected: 5.3.10-1ubuntu3.4 (Precise)
+ Affected: 5.4.6-1ubuntu1 (Quantal)
- According to the PHP documentation, the behaviour in PHP 5.4 changed:
- http://www.php.net/manual/en/function.date-default-timezone-get.php
+ Workaround: edit /etc/php5/*/php.ini, uncomment the "date.timezone" line
+ and set it to what you need.
- First I thought that it is a bug of the packages php5-cli and
libapache2-mod-php5 which do not set the date.timezone in their respective
php.ini files. You can see that if you execute the following 2 commands:
- dpkg-query --control-show libapache2-mod-php5 postinst
- dpkg-query --control-show php5-cli postinst
+ Test Case:
- There is only the default php.ini from the package copied without
- setting the date.timezone variable or let the user choose one.
+ Run:
+ $ php -r 'echo date_default_timezone_get()."\n";'
- But then I recognized, that the PHP script is executed to the end, also
- if the date.timezone variable is not set in php.ini
+ Expected results: timezone (eg. "UTC")
-
- Let me demonstrate this in 3 examples:

- I am really not sure whether this is a bug in cacti (because the graphs
- are not updated although the not set timezone in php.ini should let the
- poller finish his work) or in php5-cli/libapache2-mod-php5 (which should
- either interact with the user to ask which timezone to set in the
- php.ini or take the timezone from /etc/timezone), I just recognized that
- the graphs in cacti did not update after the release upgrade and it
- worked again after setting date.timezone in both php.ini files and
- reloading apache2.
-
- IMHO it has to be solved either in the cacti package or the bug should
- be assigned to php5-cli and libapache2-mod-php5 to let them set the
- date.timezone variable in the postinstall routine.
