docs: Appends the value of a date-time field to the formatter using a normal
  output style.
  <p>
  The value of the field will be output during a print.
  If the value cannot be obtained then an exception will be thrown.
  <p>
  The value will be printed as per the normal print of an integer value.
  Only negative numbers will be signed. No padding will be added.
  <p>
  The parser for a variable width value such as this normally behaves greedily,
  requiring one digit, but accepting as many digits as possible.
  This behavior can be affected by 'adjacent value parsing'.
  See {@link #appendValue(TemporalField, int)} for full details.
  
  @param field  the field to append, not null
  @return this, for chaining, not null
