Add timezone display setting for Table Editor timestamp columns

Hi Supabase team,

I would like to request a display setting for timestamp/timestamptz columns in the Table Editor.

Currently, timestamptz values are displayed in UTC, for example:

2026-06-12 07:00:01+00

For users in other time zones, it would be very helpful if the Table Editor allowed choosing a display timezone, such as:

• Browser local timezone
• Project/database timezone
• Custom timezone, e.g. Asia/Seoul
• UTC

This should only affect the Table Editor display format, not the stored database value.

Use case: Our database correctly stores timestamps as timestamptz/UTC, but when manually inspecting records in Table Editor, it is difficult to read operational data because our team works in Korea Standard Time, UTC+9.

Expected behavior: A dashboard-level or project-level preference like:

"Display timestamps in: UTC / Local browser timezone / Custom timezone"

Even just an option to display timestamps in the browser's local timezone would solve most of the problem.

Example:

Current display in Table Editor:

2026-06-12 07:00:01+00

If the display timezone is set to UTC+9 / Asia/Seoul, the same timestamptz value should be displayed as:

2026-06-12 16:00:01+09

The underlying stored value should remain the same. Only the Table Editor display format should change.

This would make debugging logs, daily stats, user activity, and scheduled job records much easier without changing database data.

Thank you.
