## Summary The duration chart on the Dag and Task overview pages formatted its bar labels — which Chart.js reuses as the tooltip title — in the browser's local timezone, while the x-axis ticks and every other timestamp in the UI follow the timezone selected in the header. A user in Warsaw looking at a run scheduled for 08:30 UTC saw the axis say 08:30 and the tooltip say 10:30, so the tooltip no longer identified the bar under the cursor — misleading precisely when the chart is used to compare runs. Labels now go through the same `formatDate` call with the selected timezone that the axis already used. ## Tests The component had no tests; this adds one asserting the label text across three timezones. related: #72018 --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes — Claude Code (Opus 5) Generated-by: Claude Code (Opus 5) following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) -- This is an automated message from the Apache Git Service.
