AI Summary: The task is to fix a Pandas SettingWithCopyWarning in the `seismometer` Python package. The warning occurs when converting datetime columns in a DataFrame within the `_infer_datetime` static method of the `Seismogram` class. The solution involves replacing the current assignment method with `.loc` indexing to ensure modifications are made to the original DataFrame and not a copy, thereby eliminating the warning.
