How to support multiple timezones

[emmanux]

You don't need to go distributed (Central/childs) to achieve support for multiple timezones.
It's true that the Zabbix's GUI (zabbix-frontend-php) doesn't support multiple timezones out-of-the-box, but you can get it by creating some symlinks and adding some configuration to your /etc/zabbix/apache.conf

Example

Symlinks:

/usr/share/zabbix-co -> /usr/share/zabbix
/usr/share/zabbix-ar -> /usr/share/zabbix

Modifications to /etc/zabbix/apache.conf:

<IfModule mod_alias.c>
    Alias /co /usr/share/zabbix-co
</IfModule>

<Directory "/usr/share/zabbix-co">
    Options FollowSymLinks
    AllowOverride None
    Order allow,deny
    Allow from all

    php_value max_execution_time 300
    php_value memory_limit 128M
    php_value post_max_size 16M
    php_value upload_max_filesize 2M
    php_value max_input_time 300
    php_value date.timezone America/Bogota
</Directory>

<IfModule mod_alias.c>
    Alias /ar /usr/share/zabbix-ar
</IfModule>

<Directory "/usr/share/zabbix-ar">
    Options FollowSymLinks
    AllowOverride None
    Order allow,deny
    Allow from all

    php_value max_execution_time 300
    php_value memory_limit 128M
    php_value post_max_size 16M
    php_value upload_max_filesize 2M
    php_value max_input_time 300
    php_value date.timezone America/Argentina/Buenos_Aires
</Directory>

Doing so, you got three different urls:
http://yourzabbix.server/ar (Argentina timezone)
http://yourzabbix.server/co (Colombia timezone)
http://yourzabbix.server/zabbix (default)

Each showing the same events and graphs, but according to the correct timezone.
