--kiosk-printing --kiosk "http://localhost/fastfood" TRUNCATE TABLE employee_activities; TRUNCATE TABLE expenses; TRUNCATE TABLE tbl_sales; update invoice_id set number=0; Open the httpd.conf file located in the \xampp\apache\conf\ directory. Add the following line to the file: SetEnv TZ Europe/Istanbul Open the php.ini file located in the \xampp\php\ directory. Find the [Date] section and set the date.timezone value to Europe/Istanbul. Open the my.ini file located in the \xampp\mysql\bin\ directory. Add or replace default-time-zone = "Europe/Istanbul". Restart the Apache HTTP and MySQL server. After some searching I found the solution: In httpd.conf (\xampp\apache\conf\httpd.conf) , add the following line: # Set timezone to Europe/Athens UTC+02:00 SetEnv TZ Europe/Athens Edit php.ini (\xampp\php\php.ini) date.timezone value in [Date] section: date.timezone = "Europe/Athens" You can find the available PHP timezones in http://php.net/date.timezone In my.ini (\xampp\mysql\bin\my.ini) add or replace default-time-zone = "Europe/Athens" Now restart Apache HTTP and MySQL server and you are done!
