# Chapter 13. Time

SDL provides several cross-platform functions for dealing with time. It provides a way to get the current time, a way to wait a little while, and a simple timer mechanism. These functions give you two ways of moving an object every x milliseconds:

- Use a timer callback function. This may have the bad effect that it runs in a seperate thread or uses alarm signals, but it's easier to implement.

- Or you can get the number of milliseconds passed, and move the object if, for example, 30 ms passed.
