Then you need to create a variable with the current time and apply some maths to come to the 30min before. That can range from easy to demanding, depending on what you really require. There some threads (e.g. in FAQs) dealing with date/time maths.

NAME
exfixed - Using fixed point maths. Allegro game programming library. SYNOPSIS
#include <allegro.h> Example exfixed DESCRIPTION
This program demonstrates how to use fixed point numbers, which are signed 32-bit integers storing the integer part in the upper 16 bits and the decimal part in the 16 lower bits. This example also uses the unusual approach of communicating with the user exclusively via the allegro_message() function. SEE ALSO
