https://sonarly.com/issue/24466?type=bug DATE fields displayed in RELATIVE format show the wrong day (e.g., "Today" instead of "Tomorrow") for users in timezones west of UTC, because date-only strings are parsed as UTC midnight then compared against local time. Fix: Changed the date parsing in `formatDateISOStringToRelativeDate.ts` line 22 to handle date-only strings (yyyy-MM-dd format, length 10) by appending `T00:00:00` without a trailing `Z`. This forces the `Date` constructor to interpret the string as local midnight instead of UTC midnight. Per the ECMAScript spec, `new Date("2026-04-14")` produces UTC midnight (`2026-04-14T00:00:00.000Z`), which falls on April 13 in timezones west of UTC. By appending `T00:00:00` (no `Z`), the Date constructor uses local time, keeping the date on the correct calendar day for the user's timezone. Full datetime strings (with time and timezone components, length > 10) continue to use the original `new Date(isoDate)` parsing, preserving correct behavior for the `formatDateTimeString` caller that passes datetime values. This matches how the other format branches (USER_SETTINGS, CUSTOM) already handle timezone correctly via `formatInTimeZone` with explicit timezone parameters.

Why Twenty
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
