fix(tables): use explicit timestamps for expiration

apps/docs/content/docs/tables/index.mdx

@@ -24,9 +24,12 @@ Every column has a type, which decides how its values are stored and validated.
 | **Currency** | An amount in a currency you pick per column | `$1,234.56` |
 | **Boolean** | `true` or `false` | `true` |
 | **Date** | A date | `2026-03-16` |
+| **Expiration** | A timestamp with an explicit timezone offset that schedules row deletion | `2026-03-16T14:30:00-07:00` |
 | **JSON** | An object or array | `{ "tier": "pro" }` |
 | **Select** | One of a fixed set of options, or several | `Pro` |
 
+Expiration accepts valid ISO timestamps with `Z` or an explicit numeric UTC offset, such as `2026-03-16T14:30:00-07:00`. Seconds are optional; fractional seconds support up to six digits. Values preserve their supplied clock time and numeric offset without losing fractional precision; `Z` is stored as `-00:00`. For example, `2026-03-16T14:30:00-07:00` and `2026-03-16T21:30:00Z` represent the same deadline and compare equally. Epoch numbers and timezone-free dates are not accepted. The picker retains the stored offset; cells, clipboard values, and exports use that offset too. Picking a day without a time uses midnight in that offset. New picker values default to `-00:00`. Numeric offsets are fixed: editing a date does not automatically switch between summer and winter offsets. A table can have one Expiration column. An empty expiration leaves the row unexpired; on an update, omit the field to preserve it or set it to `null` to clear it. Expired rows are removed by periodic cleanup, subject to the table's delete lock.
+
 Types are enforced as you enter values, so a Number column only takes numbers.
 
 A Currency column stores a plain number and renders it in the currency you choose for that column, so filters, sorts, and exports all see the amount itself. Changing a column's currency relabels it — it does not convert the amounts.
