# Global Variables

The global namespace has a bunch of useful variables.



:::info
I don't love these names but they're not going to go anywhere, so you're free to use them. In all likelihood in the future we'll get together and create a bunch of nicer #define's for them, so `g_flTime` will be accessible via`Time.Now`, or just `time` etc.
