Gets the value of the specified field from this instant as a {@code long}.
!(p)
This queries this instant for the value of the specified field.
If it is not possible to return the value, because the field is not supported
or for some other reason, an exception is thrown.
!(p)
If the field is a {@link ChronoField} then the query is implemented here.
The {@link #isSupported(TemporalField) supported fields} will return valid
values based on this date-time.
All other {@code ChronoField} instances will throw an {@code UnsupportedTemporalTypeException}.
!(p)
If the field is not a {@code ChronoField}, then the result of this method
is obtained by invoking {@code TemporalField.getFrom(TemporalAccessor)}
passing {@code this} as the argument. Whether the value can be obtained,
and what the value represents, is determined by the field.
@param field the field to get, not null
@return the value for the field
@throws DateTimeException if a value for the field cannot be obtained
@throws UnsupportedTemporalTypeException if the field is not supported
@throws ArithmeticException if numeric overflow occurs
