[php-maint] Bug#571762: Bug#571762: [php5] please get rid of "Warning: date() [function.date]: It is not safe to rely on the system's timezone settings."

[Martín Marqués]

FYI, I'm unable to eliminate this annoying message from the PHP CLI 
(apache stopped sending messages the moment I configured date.timezone = 
'America/Buenos_Aires'), but using this same configuration on 
/etc/php5/cli/php.ini doesn't stop PHP from sending warnings when 
executed from the command line.

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 'America/Buenos_Aires' 
for 'ART/-3.0/no DST' instead in /usr/share/php/Date/TimeZone.php on 
line 4717

Something is wrong here.
