## Problem The dashboard renders all timestamps in the browser's local timezone. When debugging app issues, users often want to see logs and timestamps in a different timezone (e.g. their app's deployment region) without changing their OS clock. ## Fix - New Timezone submenu in the user-avatar dropdown, sitting next to the existing Theme picker. Search-as-you-type combobox over the full IANA catalog plus an Auto detect option. - Selection persists in localStorage (`supabase-ui-timezone`) and survives `clearLocalStorage()`. No backend schema change. - New `lib/datetime.tsx` exposes pure timezone-aware formatters (`formatDateTime`, `formatDate`, `formatTime`, `formatFromNow`, `toTimezone`) plus a `TimezoneProvider` and matching React hooks (`useTimezone`, `useFormatDateTime`, ...). The pure functions take `tz` explicitly so they're easy to unit test (17 vitest cases covering DST transitions, multi-tz formatting, unix-micro/Date inputs, invalid-tz fallback). - The selected timezone propagates to every existing `<TimestampInfo>` in Studio via a new `TimestampInfoProvider` context exported from `ui-patterns`. No per-callsite changes needed for those ~20+ surfaces. - The `UnifiedLogs` date column migrates off `date-fns` to the new `useFormatDateTime` hook (the rest of the date-fns callers stay as-is, since they're either internal range math or non-display). - `ALL_TIMEZONES` (~600 entries) moves out of `PITR.constants.ts` into a shared `lib/constants/timezones.ts`. PITR keeps a re-export shim so its callers don't move. New `TIMEZONES_BY_IANA` dedupes the catalog by primary IANA name (the original list contains both PDT and PST rows for `America/Los_Angeles`, etc.) and `findTimezoneByIana` provides reverse lookup. - Telemetry: `timezone_picker_clicked` PostHog event with `previousTimezone`, `nextTimezone`, `isAutoDetected` properties. Notes for reviewers: - Bare `dayjs(x).format(...)` calls (~157 files) intentionally still render in browser-local time. Surfaces opt in by switching to the new wrappers, so this PR is the abstraction plus logs adoption; broader migration is a follow-up. - Two `// prettier-ignore` lines (`apps/studio/pages/_app.tsx`, `apps/studio/components/interfaces/UnifiedLogs/UnifiedLogs.fields.tsx`) work around a pre-existing local-tooling issue where `prettier-plugin-sql-cst` strips angle-bracket type arguments under certain conditions. Project's pinned prettier (3.8.1) does not strip; the issue surfaces with a globally-installed prettier. Worth tracking separately. - Hydration: `guessLocalTimezone()` and `useLocalStorageQuery` are client-only. Studio is mostly CSR via the Pages Router, but any SSR'd `<TimestampInfo>` may briefly render in the server's tz before client hydration. Existing behavior already had this mismatch with `.local()`; this PR does not regress it. - Backend timestamps round-tripped through query params and mutations stay UTC. The picker is display-only. ## How to test - Run `pnpm dev:studio`, sign in. - Open the user avatar dropdown (top right). Hover Timezone. - Search for "tokyo", pick `(UTC+09:00) Osaka, Sapporo, Tokyo`. - Open any project, navigate to Logs (e.g. `Project > Logs > Edge Functions`). Hover a log row's timestamp; the popover should show UTC, the chosen tz (`Asia/Tokyo`), and the relative time. Visible cell text should be in JST. - Visit any page that uses `<TimestampInfo>` (Database > Backups, Project Pause state, Edge Function details). Same tooltip should reflect Asia/Tokyo. - Refresh the page; timezone is still Asia/Tokyo. - Reopen the picker, choose Auto detect; timestamps revert to browser local. - Run `pnpm --filter studio test lib/datetime.test.ts`. 17 tests should pass. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Timezone selector added to the user menu with auto-detect and manual override * App-wide timezone provider and hooks plus a shared timezone catalog for consistent timezone-aware display * Timestamp components accept an optional timezone prop and respect user preference (persisted) * **Bug Fixes / Improvements** * Logs and timestamp displays now use the new timezone formatting hooks * **Tests** * Added comprehensive datetime and timezone catalog tests * **Telemetry** * Telemetry event added for timezone picker interactions <!-- end of auto-generated comment: release notes by coderabbit.ai -->
Writing pages
Rough guidelines
- Try to break down your pages into smaller building blocks - components which are tightly coupled to a page can be placed within the folder
components/interfaces/xxx/...(Refer to the README.md under the components folder) - Keep to using
useStatehooks for any UI related logic, do not create MobX local stores to handle UI logic.
Template for building pages
import { NextPage } from 'next'
import { withAuth } from 'hooks/misc/withAuth'
// Import the corresponding layout based on the page
import { Layout } from 'components/layouts'
// Import the main building blocks of the page
import { ... } from 'components/interfaces/xxx'
// Import reusable UI components if needed
import { ... } from 'components/ui/xxx'
// Name your page accordingly
const Page: NextPage = () => {
return (
<Layout>
<div>Page content</div>
</Layout>
)
}
export default withAuth(Page)
