Description

A Zendesk user reported a problem with this timeline. The first couple of events are hundreds of millions of years ago. Then, there is one which is 20,000 years ago.

One problem is that there is a tick labeled 1000.0 KYA when the neighboring ticks are in MYA -- shouldn't this one be 1 MYA?

The other problem is that as one zooms in on the timeline, we never get new ticks at a more appropriate resolution.

Research direction

Reproduce the behavior using the linked TimelineJS embed, focusing on the cosmological dates, the 1000.0 KYA label, and zooming around the 20,000-years-ago event. Trace the timeline's axis tick generation and date formatting from the JavaScript entry points, then verify that labels use an appropriate unit and that zooming produces finer-resolution ticks.
