Since `dask_array_type` is a `tuple`, `hasattr`will always return `False`.

Wrapping a `datetime` in a quantity does not really make sense so I'll try to remove those tests.

Note that none of them will fail with `dask` installed (which is why we didn't catch this with CI):
without `dask`:
```python
d = np.datetime64(""NaT"", ""ns"")
v = xr.Variable([""x""], ureg.Quantity([d], ureg.m))
assert v.equals(v.copy())  # AssertionError
```
with `dask`, `equals` returns `True` and the tests pass.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,567058587
