era: Years with an Era
Provides a consistent vector representation of years with an
associated calendar era or time scale. It includes built-in definitions of
many contemporary and historic calendars; time scales commonly used in
archaeology, astronomy, geology, and other palaeosciences (e.g. Before
Present, SI-prefixed 'annus'); and support for arbitrary user-defined eras.
Functions for converting between eras and for type-stable arithmetic with
years are also provided.
