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
```
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?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,401392318
