Hmmm. The ability to show continental drift using a timeline probably
doesn't need a datetime (century is usually pretty fine-grained). But
virtual skies are pretty important to historical as well as future stuff.
There must be about half a billion people who would like to be able to
recreate the night skies around Bethlehem in a period between say
-0010-01-01 and 0004-01-01 to see if there is something interesting
There are various ecological things that are well-suited to timelines
stretching back 2009 years. Urban planning and economics is another area
that may use the ability to look at things 2009 years ago. Historical
weather modelling is another - there are points in history where the date
is actually relevant, in particular the ability to match up phenomena
known to have occurred in order to synchronise dates calculated according
to different and not entirely-known methods.
As an historian, these seem useful things to be able to do. It would seem
to me as a browser maker that this doesn't actually complicate life a
whole lot (I may be wrong - I haven't thought hard about the implications
yet). As a standards guy, I do not see that being able to do this would
introduce any particular complications (beyond a few more test cases). I
am inclined to think that the use cases justify the cost, at least enough
to investigate further.
