Hello
create a PHP.ini or edit if there is already one in your root directory and add/edit this line
date.timezone = "Africa/Lome"
this should make your website using the timezone of Lome.
it is possible that your hosting provider does not allow you to change the timezone with the php.ini file
try to set the timezone with .htaccess file , add this line or edit it if it already exist in your .htaccess file on your root directory
SetEnv TZ Africa/Lome
