By default, Pandora FMS Console web uses the default timezone on PHP, and if it’s not set up (not default), it’s forced to be in the European Time zone. To modify this, edit the file include/config_process.php, and input your own timezone, for this example Mexico City:
if (ini_get('date.timezone') == ""){
date_default_timezone_set("America/Mexico_City");
# date_default_timezone_set("Europe/Berlin");
}
