  ! dc_date_types#DC_DIFFTIME 型変数を文字型変数へ変換して返します.
  ! 書式は以下のようになります.
  !
  !   +YYYY-MM-DDThh:mm:ss.s
  !   -YYYY-MM-DDThh:mm:ss.s
  !
  ! YYYY は年, MM は月, DD は日, hh は時, mm は分, ss.s は秒を表します.
  ! ただし, DD は 2 桁を超える場合があります.
  ! (dc_date_types#DC_DIFFTIME は X ヶ月後, X 日前, などを表現するため
  ! のデータ型なので, 日を月に繰り上げたり, 月を日に繰り下げることを
  ! しません. また「年」の情報も持ちません. 1 年の日数や 1 月の日数は
  ! dc_date_types#DC_DATETIME 側で決まります).
  !
  ! なお, DCDiffTimeCreate において, 単位を '1' とした場合は無時限時間と
  ! 扱うため, 以下のような書式となります.
