polars_ops::chunked_array::replace_time_zone already deals with unsetting the sortedness flag if necessary, so this can now be simplified
there's already tests which check sortedness for replacing the time zone:
- test_replace_time_zone_sortedness_series
- test_replace_time_zone_sortedness_expressions

@orlp I think this is what you were asking for? like this, the example shows why the sorted flag shouldn't be preserved for 'Europe/London'

Can you rebase? |
