Hi Not taking a position, but one possibility as the user of the database is to install a file or bundle with your application the locale you want. You can easily and a new zone anytime you feel like deviating from the norm. Just make sure to bundle with an installer. Myself, I have patches to the database to create a database. It then gets installed on a system. I also use the patched files and zic so that, if using a different application, it can access the Olson database along with any changes or new information. This doesn't just apply to a database, including compatibly source code has been done for ages. Hope this helpful, just add a patch to backwards file with your new link, or bundle with your app, depending on how you need to use. Steve
