parameters: (arr_or_dtype)
return_statement: return _is_dtype(arr_or_dtype, lambda dtype: dtype == _TD_DTYPE)
docstring: Check whether the provided array or dtype is of the timedelta64[ns] dtype.
  
      This is a very specific dtype, so generic ones like `np.timedelta64`
      will return False if passed into this function.
  
      Parameters
      ----------
      arr_or_dtype : array-like
          The array or dtype to check.
  
      Returns
      -------
      boolean
          Whether or not the array or dtype is of the timedelta64[ns] dtype.
  
      Examples
      --------
      >>> is_timedelta64_ns_dtype(np.dtype('m8[ns]'))
      True
      >>> is_timedelta64_ns_dtype(np.dtype('m8[ps]'))  # Wrong frequency
      False
      >>> is_timedelta64_ns_dtype(np.array([1, 2], dtype='m8[ns]'))
      True
      >>> is_timedelta64_ns_dtype(np.array([1, 2], dtype=np.timedelta64))
      False
docstring_summary: Check whether the provided array or dtype is of the timedelta64[ns] dtype.
