[repo:objectui] Pure date fields within ±7 days render as relative text ('3天前') in lists and detail — unconditional in the date formatter, so a period-end business date loses its value #14885

Summary

A pure date field (no time component, a business date such as a period end) is rendered as relative text whenever the value is within ±7 days of today: 3天前, 明天, 昨天. Outside that window it renders the calendar date. In a list this produces two visually different formats in the same column set, and the relative text hides the actual date a user needs to read (an assessment period end is a business date, not a "how long ago" fact).

Minimal reproduction

Platform 17.2.0 console, today = 2026-09-03.

Object kpi_plan with period_start: Field.date({ label: '周期开始' }) = 2026-08-01 and period_end: Field.date({ label: '周期结束' }) = 2026-08-31.

List view columns period_start, period_end:

周期开始   8月1日      ← calendar date (34 days ago, outside the window)
周期结束   3天前       ← relative (3 days ago, inside the window)

Detail page shows the same. The audit timestamps (created_at etc.) are datetimes and are a separate case.

Where

ui-components chunk, date display formatter:

function Ltt(e, t) {
  ...
  let o = Math.round((dateOnly(value) - dateOnly(today)) / 864e5);
  if (o < -7 || o > 7) return k9(n, void 0, t);          // calendar date
  if (o < -1 && t?.dueLike) return t.t('fields.relativeDate.overdue', {count: -o}) ...
  return Itt(o, t?.locale);                               // Intl.RelativeTimeFormat(..., 'day')
}

The relative branch is unconditional for the ±7-day window; dueLike only changes the wording.

Expected

• date fields render the calendar date by default, in both list cells and detail pages. A business date is a value the user reads and compares; relative wording loses the value.
• Relative wording should be opt-in per field / column (e.g. display: 'relative', or only when the field is flagged dueLike), or shown as a secondary hint (tooltip / muted suffix) next to the actual date.
• If the default must stay relative, at least apply it consistently (both 8月1日 and 3天前 in one row is the worst of both).
