Idea or Bug.
Time functionality in ArcGIS desktop and ArcGIS Server requires times in UTC. This is very limiting for displaying historical, archaelogical, geological or futuristic data.
UTC has an earliest date of 1700-01-01T00:00:00Z GMT, or just after midnight on January 1, 1700.
There really needs to be a way to deal with time data from any date, both in arcmap and arc server js api.
This is a huge issue for us at the Utah Geological Survey in Utah.
