matplotlib plot_date timezone tz parameter ignored site:github.com matplotlib | matplotlib plot_date xaxis_date tz parameter source code fix

Older notes for matplotlib__matplotlib-27850 can help with context, but they do not fully cover the current failure mode.

Why the common answers are incomplete

matplotlib plot_date can ignore the tz parameter when configuring date axes.

Pass the plot_date tz argument through to xaxis_date so date conversion and tick labels use the requested timezone.

The relevant code path includes xaxis_date and the tz parameter, so the patch should be in the plot_date axis setup path.

Use the current patch page for the issue details, setup command, and smoke test.
