Dear John
Im not sure I can actually implement prefixes for calendar fields,
since in general that would violate the need for integers.
millisecond makes sense, but millihour doesnt.
Yes, I see. Could we include ms then, and also a, ka and Ma for a year,
1000 years and a million years, used in paleoclimate?
i will add ms.
im not familiar with a, ka, and Ma. what are those?
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?
Thanks for your other replies as well.
Best wishes
Jonathan
