ALLEGRO_TIMER *al_create_timer(double speed_secs)

Allocates and initializes a timer. If successful, a pointer to a new timer object is returned, otherwise NULL is returned. speed_secs is in seconds per “tick”, and must be positive. The new timer is initially stopped.

Usage note: typical granularity is on the order of microseconds, but with some drivers might only be milliseconds.
