Regarding paleoclimate, a point I forgot is that some modellers may
wish to
have years which are very large negative numbers (many more than four
digits)
if they set up the model with the "true" date for the run. Although for
geological timescales you might say that this isn't necessary and you
might
as well choose an arbitrary year, there is a good reason for it in
Pleistocene
when you might be using the dates to relate to orbital forcing or
atmospheric
composition.
so the idea is that you are simulating some year, so you really need
time down to the hour or second. but the climate is from 5 million
years ago, so you need the year field to be able to handle that?
Im just thinking that fitting this into the ISO date format
"5000000-01-01 12:00" seems awkward, esp as it indicates unwarranted
precision.
seems something like "01-01 12:00 reference 50m BCE" would be better.
What do paleo modellers actually use, eg in the figures that they publish?
