Editing php.ini to set the timezone

When I re-installed php, I got this error when rendering Ipeer.

( ! ) Warning: strtotime() [function.strtotime]: 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 'America/Los_Angeles' 
for 'PDT/-7.0/DST' instead in /srv/http/compatibility/cake/basics.php on line 796

So I modified this in /etc/php/php.ini to fix it:

[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone = "America/Vancouver"

(Use your own timezone, obviously. :-)
