Thanks for the clarification! I think the tolerance argument might even be superior to the limit or to say the least, the resample methods would benefit from any of these arguments.

My above mentioned changes to the code, despite mixing up limit and tolerance, actually seem to implement the tolerance argument.

```python import xarray as xr import pandas as pd import datetime as dt

dates=[dt.datetime(2018,1,1), dt.datetime(2018,1,2)] data=[10,20] df=pd.DataFrame(data,index=dates) xdf = xr.Dataset.from_dataframe(df) xdf.resample({'index':'1H'}).nearest(tolerance=dt.timedelta(hours=2)) ``` would lead to

<xarray.Dataset> Dimensions: (index: 25) Coordinates: * index (index) datetime64[ns] 2018-01-01 ... 2018-01-02 Data variables: 0 (index) float64 10.0 10.0 10.0 nan nan ... nan nan 20.0 20.0 20.0

Would that be helpful to include and write a pull request?
