One idea and use case for Paleontologists and Geologists coming over to Rust in droves... :-)
Generically, just be able to handle simple Geologic addition and subtraction against an Epoch itself (reference date) http://en.wikipedia.org/wiki/Epoch_(reference_date) using known abbreviations. And additionally, store, understand, and output them: B.Y.B.P = Billion Years Before Present M.Y.B.P = Million Years Before Present On Fri, Sep 13, 2013 at 2:51 PM, Aaron Dandy <aaron.da...@live.com> wrote: > I remember reading this article: > http://noda-time.blogspot.com/2011/08/what-wrong-with-datetime-anyway.html a > while back and really appreciating date time & time zone libraries.
