It has been noted that to support the entire date range of earth’s history, we’ll need an approach that does not totally rely on date objects. A reasonable approach is to use a big integer (or long) that represents the number of seconds before or after 1970-01-01. This allows us to use date objects with little effort when a value is within the supported range and to use a date-like object (ignores things like leap-year, etc.) when the value is outside of that range.
