100980878,MDU6SXNzdWUxMDA5ODA4Nzg=,531,Having trouble with time dim of CMIP5 dataset,1151830,closed,0,,,3,2015-08-14T10:11:32Z,2015-08-26T04:40:09Z,2015-08-26T04:40:03Z,NONE,,,,"Hi guys,

I was trying to use xray to look at CMIP5 data (e.g. https://dl.dropboxusercontent.com/u/1392864/rlut_Amon_BCC-bcc-csm1-1_rcp85_r1i1p1.nc), and the time dimension seems to fail. If I call

```
>>> dset[""time.year""]
  ...
  File ""/usr/local/lib/python2.7/site-packages/xray/core/dataset.py"", line 59, in _get_virtual_variable
    data = getattr(date, var_name)
AttributeError: 'Index' object has no attribute 'year'
```

And thereafter I get

```
>>> dset
  ...
  File ""/usr/local/lib/python2.7/site-packages/xray/core/indexing.py"", line 371, in __array__
    return self.array.values.astype(dtype)
TypeError: Cannot cast datetime.date object from metadata [D] to [ns] according to the rule 'same_kind'
```

Is this all because the run goes to 2300?

Thanks!
     Jonah
