A fork for the time-zone database?

As one datapoint, nowadays I need to provide all three of my "first" names on banking-related douments because of the current crop of gobsmackingly dumb regulations. But nobody should ever use anything but the second of those names to address me. No, not the first, and certainly not all three, I'm not the male equivalent of Pippi Longstockings dammit.

Now this is certainly a First World Problem compared to people who are named O'Hare and cannot even enter that due to broken Bobby Tables Prevention filters, much less my acquaintance Aahz (yes that's his single real-life name), or … the list goes on.
