%description
Provides a consistent representation of year-based time scales as a
numeric vector with an associated 'era'. There are built-in era
definitions for many year numbering systems used in contemporary and
historic calendars (e.g. Common Era, Islamic 'Hijri' years); year-based
time scales used in archaeology, astronomy, geology, and other
palaeosciences (e.g. Before Present, SI-prefixed 'annus'); and support for
arbitrary user-defined eras. Years can converted from any one era to
another using a generalised transformation function. Methods are also
provided for robust casting and coercion between years and other numeric
types, type-stable arithmetic with years, and pretty-printing in tables.
