Description

Per the code:

TODO We need a better way to infer whether the ordinal scale is UTC or local time.

Currently we support the default time format for ordinal scales when we can infer a time interval, but we always use UTC time. How could you indicate that you want to show the times in local time? Or should this be based on supporting an arbitrary time zone at the Plot level? #531 Alternatively, should we expose Plot’s default time formats as reusable implementations?

Research direction

Start with the TODO and the current default time-format behavior for ordinal scales. Compare local-time handling, Plot-level arbitrary time zones, and reusable default formats; the issue is done when one API direction and its expected behavior are clearly specified and implemented.
