I just clicked on that and I get

Cannot GET /help/

It's encrypted with Letsencrypt so something at the server end isn't 
delivering the page

The manual entry field also supports rolling digits up and down, which is a fun way to explore how the sky changes as you change latitude and longitude.

There’s a file named “northamerica”, and inside that file, a zone entry named "America/New_York”. Perhaps that’s still something a bit too rawly technical to be considered user-friendly, however.
