 These readers parsed a `YYYY-MM-DD` value with the engine's own `Date` parse, which reads it as UTC midnight, so every viewer west of UTC saw the day before. Each now reads the value through `toDisplayDate` from `@object-ui/core`, which rebuilds a date-only value at local midnight of the day it names. A value with a time part keeps its instant.
 
-- **Timeline.** The object timeline's date bucket, its sort and the item date the renderer prints read the value that way. West of UTC an item due today no longer sits under "Overdue", one due tomorrow no longer sits under "Today", and the `short` and `long` item faces print the stored day. The `iso` face prints a date-only value's day from local getters, and an instant's UTC day as before. A day its month does not have, such as `2026-02-30`, is no longer rolled into March: the item sits under "No date", sorts with the dateless items, and its `short` and `long` faces are the ones an unparsable value already had. An unparsable value now sorts with the dateless items too, and the `iso` face prints such a value as written where it used to throw. The gantt variant's axis headers and extent are not changed here.

An unparsable value now sorts with the dateless items too, and the `iso` face prints such a value as written where it used to throw. The gantt variant's axis headers, extent and bar positions are not changed here, so west of UTC its bar tooltip, which prints through the same item-date function, now names the stored day while the axis above it still reads the day before, until a later slice of objectui#10866.
 - **Charts.** A date-only category on the x axis reads `Sep 1` for `2026-09-01`, and `Sep 2026` on a month-grained axis, in every zone. When the display locale is a tag `Intl` refuses, the tick still prints the stored day: it reads the local-midnight value with local getters, because its `toISOString()` would name the day before east of UTC. An instant's fallback keeps its UTC day. A date-only category naming a day its month does not have falls back to the raw category, the face any other non-date category gets, instead of the rolled day.
 - **i18n helpers.** `formatDate`, `formatDateTime`, `formatRelativeTime` and `formatDateSpec` read a date-only string as the day it names: `formatDateTime` shows midnight of that day, and `formatRelativeTime` counts to the start of it. `formatDateSpec` applies its `timeZone` to an instant only, and formats a date-only value in the local zone, where the shared step's local midnight reads back as its day; a `timeZone` west of UTC no longer turns `2026-09-01` into August 31st for every viewer. All four return a day its month does not have as the raw string. `formatRelativeTime` now returns an unparsable value as its string, the face the other three already gave one, where it used to throw a `RangeError`.
