Measured entry

kibo-relative-time

cardminimal-flat

A compound React client component for showing one time across multiple named time zones, with separate label, time, and date parts. It ships as copied registry source and formats values with the browser Intl API. It depends on React, Radix's controllable-state hook, Tailwind utility classes, and a cn helper backed by clsx and tailwind-merge.

Verdict

A sound small utility for dashboards and team-presence cards: it builds, mounts, and exposes useful controlled formatting hooks. Adopt it when its copy-in Tailwind structure suits your stack, but plan a responsive pass and locale changes before using it in a broad public interface.

Use it if

  • You need a compact office-hours or distributed-team time-zone list.
  • You want either a live internal clock or a controlled date shared across several zones.
  • Your design system already uses Tailwind utilities and composable React primitives.

Skip it if

  • The card must fit narrow screens unchanged, since the supplied composition overflows there.
  • You need locale selection without editing the source, because formatting is fixed to US English.
  • You require semantic time elements or machine-readable timestamps; the supplied parts render plain divs.

In a non-shadcn project, add the Radix controllable-state package, clsx, and tailwind-merge; provide the cn utility or replace its import; configure Tailwind for the included classes and theme tokens; and keep the file in a client-rendered React boundary.
