[dev] Problem installing Horde

[Weplica]

Hello,

I hope I am not off-topic, I need help to install Horde on my server CentOS 6.

I have tow problems, the first, when I do "webmail-install" I have a  
lots of this warnings:

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/Lima' for  
'PET/-5.0/no DST' instead in /usr/share/pear/Horde/Log/Logger.php on  
line 182
