# feat(topic): show the last successful load time
## Summary
Show the time of the last successful topic list load in the Topic page
header. The page records `Date.now()` only when `loadTopicPage` succeeds for
the latest request; a failed load (or a stale response) leaves the previous
successful time untouched. The timestamp is rendered as "最近更新 HH:mm:ss"
(`common.lastUpdated` i18n key, zh/en) next to the page title, using the local
clock of the browser.
Note: the Topic page has no dedicated refresh button (the list reloads when
instance/search/type/pagination change), so the indicator is placed in the
header/title area via the existing `PageHeader` `extra` slot.
## Why
Users cannot tell whether the topic list on screen is current. Surfacing the
last successful load time next to the title makes staleness visible without
adding a new refresh control or changing the existing reload triggers.
## Testing
- `cd web && ./node_modules/.bin/tsc -b tsconfig.app.json` passes (exit 0).
- `./node_modules/.bin/vitest run
src/pages/instance/__tests__/TopicPage.test.tsx` passes: 24/24 (run on the
Linux test server with Node 20).
- New cases:
- `shows the time of the last successful list load in the header` – with
`vi.setSystemTime`, a successful load renders "最近更新 09:15:42".
- `keeps the previous successful load time when a reload fails` – after
the clock advances, a rejected reload leaves "最近更新 09:15:42" visible and never
shows the later time.
