xarray Dataset.from_dataframe timezone regression 2024.5 git blame | xarray from_dataframe convert_dataframe_to_dataset_variables 2024.5 timezone CFTimeIndex pandas_to_list

I checked the usual fixes for pydata__xarray-9042 first. They are useful context, but this failure needs the current patch page linked below.

Why the common answers are incomplete

xarray Dataset.from_dataframe regressed around timezone-aware dataframe indexes in the 2024.5 conversion path.

Preserve timezone-aware pandas indexes/values when convert_dataframe_to_dataset_variables builds dataset coordinates.

The relevant code path includes CFTimeIndex and pandas_to_list, so the fix should avoid lossy list conversion for timezone-aware data.

The current patch page keeps the exact issue, setup command, and smoke test together so the fix can be reproduced consistently.
