#### *property* CFTimeIndex.values

Return an array representing the data in the Index.

#### WARNING
We recommend using `Index.array` or
`Index.to_numpy()`, depending on whether you need
a reference to the underlying data or a NumPy array.

#### Versionchanged
Changed in version 3.0.0: The returned array is read-only.

* **Returns:**
  **array** ([`numpy.ndarray`](https://numpy.org/doc/stable/reference/generated/numpy.ndarray.html#numpy.ndarray) or `ExtensionArray`)

#### SEE ALSO
