title: Where the heck do I get `tzfile.h`?
body: <p>I am on Ubuntu 16.04 and I am trying to compile a program that requires a header called <code>tzfile.h</code>. Problem is I can't find a Ubuntu package for it and the place it tells me to download the "tzcode" package from, <code>ftp://elsie.nci.nih.gov/pub/</code>, <em>is dead</em>. Where do I get this file from? I want to be able to properly install it, too. Not just download it to my downloads folder.</p>
