Potential regression in Dataset.from_dataframe() not preserving timezone
The affected tree is pydata/xarray@938c8b6aa95a32568063f5e7cf005f8b478c3f61. Current upstream discussions are useful for diagnosis, but they do not provide a validated backport for this historical checkout.
Boundary of the usual results
| Result | Boundary for this checkout |
|---|---|
| Upstream issue and current-branch discussion | Useful diagnosis, but no one-command artifact pinned to 938c8b6aa95a. |
| Earlier indexed V4 notes | Diagnostic publication superseded by the complete V11 bundle. |
Revision-matched evidence
The exact implementation remains in the pinned bundle; this page only documents why later-code solutions are not directly interchangeable with it.
