It's an issue with how I am using `np.timedelta64` then. I (stupidly) assumed that `np.timedelta64` has the same call signature as `datetime.timedelta`. It appears that `np.timedelta64` silently ignores any kwargs 😕 Anyway, I won't be making that mistake again.

Once I remove timezone information from my datetime object it works just fine. Looking at https://github.com/pydata/xarray/issues/2512 it looks like the change which is required might be in `xarray/core/variable.py` (https://github.com/pydata/xarray/blob/master/xarray/core/variable.py#L165).

I'm looking at absolute temperature perturbations and bottleneck's implementation together with my data being loaded as `float32` (correctly, as it's stored like that) causes an error on the size of the perturbations I'm looking for. Example: ``` In [1]: import numpy as np ...: import bottleneck In [2]: a = 300*np.ones((800**2,), dtype=np.float32) In [3]: np.mean(a) Out[3]: 300.0 In [4]: bottleneck.nanmean(a) Out[4]: 302.6018981933594 ``` Would it be worth adding a warning (until the right solution is found) if someone is doing `.mean()` on a `DataArray` which is `float32`? Based a little experimentation (https://gist.github.com/leifdenby/8e874d3440a1ac96f96465a418f158ab) bottleneck's mean function builds up significant errors even with moderately sized arrays if they are `float32`, so I'm going to stop using `.mean()` as-is from now and always pass in `dtype=np.float64`.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,218459353
