 131      * All fields can be expressed as a {@code long} integer.

 134      * If the date-time cannot return the range, because the field is unsupported or for

 136      * <p>
 137      * Note that the result only describes the minimum and maximum valid values
 138      * and it is important not to read too much into them. For example, there
