Your "utc" local var is hiding your "utc" function argument...which I
imagine isn't what you want?

Hmmm...shouldn't the C part of it go something like this:

	void get_localtime(int utc) {
	   int seconds = utc;
	   struct tm *ltime = localtime(&seconds);
	}

But I've not used Inline yet, so I'm not sure what those
Inline_Stack_Vars & Inline_Stack_Item guys do, but I'd bet they're not
being used quite right.
