Description

I have data loaded as DatetimeNoLeap that is not recognized by PyArrow.

Should this be supported by Apache Arrow?

This happens when I call pyarrow.array(data)
```

File "pyarrow/array.pxi", line 301, in pyarrow.lib.array
File "pyarrow/array.pxi", line 83, in pyarrow.lib._ndarray_to_array
File "pyarrow/error.pxi", line 84, in pyarrow.lib.check_status
pyarrow.lib.ArrowInvalid: Could not convert 2018-01-13 09:00:00 with type cftime._cftime.DatetimeNoLeap: did not recognize Python value type when inferring an Arrow data type
```
