That discussion focuses more on using the bounds to properly weight points when resampling. 

But we could also make `.cf.resample` generate time bounds and set appropriate attributes on the returned object.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,332018176

Note, that not only resample operations should modify the time_bounds, but also the reselect process should take care about time_bounds. As an example, we assume to have in one file A instantenous data (two times a day at 00 UTC and 12 UTC) and in the other file B aggregated data (daily averages with time stamps defined at the end of the aggregation interval). The reselection process of A in B should pick up only the times 12 UTC from file A (or even better: no time steps because aggregation interval in file B is not compatible with instantenous values).

These were intentional design choices to keep xarray simple, but in principle you could layer cf convention handling on top of xarray.

Nor does it bring along bounds variables when extracting variables from a dataset, e.g.
```
        double time(time) ;
                time:long_name = ""time"" ;
                time:cartesian_axis = ""T"" ;
                time:calendar_type = ""NOLEAP"" ;
                time:bounds = ""time_bounds"" ;
                time:units = ""days since 0001-01-01"" ;
                time:calendar = ""NOLEAP"" ;
```
When a variable using the `time` dimension is extracted from a `Dataset`, the `time_bounds` variable is missing.

Is this also an intentional choice or something that xarray could/should support? Or does already and I've missed how to invoke this.

Edit: I've just realised, how is xarray supposed to ""bring along"" another variable in a DataArray object? I'll leave this query as maybe there is a solution? Have a `bounds` attribute similar to the `coords` attribute?

Is this just a dupe of https://github.com/pydata/xarray/issues/1475 ?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,332018176

For this sort of analysis, using a tool like Iris designed to follow cf conventions might make sense.
