IsoEra

An era in the ISO calendar system.
The ISO-8601 standard does not define eras.
A definition has therefore been created with two eras - 'Current era' (CE) for
years on or after 0001-01-01 (ISO), and 'Before current era' (BCE) for years before that.
| year-of-era |
era |
proleptic-year |
| 2 | CE | 2 |
| 1 | CE | 1 |
| 1 | BCE | 0 |
| 2 | BCE | -1 |
Do not use ordinal() to obtain the numeric representation of IsoEra.
Use getValue() instead.
