Time Slider: There is no year 0 #44

Closed gregallensworth closed 4 years ago

gregallensworth commented 5 years ago

In the Gregorian calendar there is no year 0.

Dates skip directly from -0001-12-31 to 0001-01-01
The delta between June 30 +1 and June 30 -1 is not 2 years, but 1 year.

For UI purposes, this is an Interesting quirk, since input[type-"range"] form controls do not allow for individual values being skipped. It may be necessary to write something new completely from scratch.

Seems like we've adapted to this OK for now. Closing out until there's a clear need to address this date problem.
