DateTime Picker
A time field in hh : mm segments with AM/PM, and a date from the Layro Calendar beside it. Type 9 and it moves to the minutes, arrows step by your minute interval, the clock opens a list of times for a mouse or a phone, and a time zone shows as a label.
The decision inside it
Nothing is sent until the time is whole
A half-typed time stays inside the field, so your form never receives midnight because someone typed one digit. The value is set with setHours on a copy of the day, so a daylight-saving day keeps the time the reader typed.
When to use it
Use DateTime Picker for a time, or a date and a time together: typed segments with arrow-key stepping, 12 or 24 hours, a minute step, and a time-zone label. For a date alone, use Date Picker.
Installation
How you get it
Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.
Use Layro's DateTime Picker for this.
Install it: npx shadcn@latest add @layro/datetime-picker
(the @layro registry is set up in components.json, with LAYRO_KEY in .env.local)
Import it from @/components/ui/datetime-picker.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Free components install through the @layro registry with your CLI token: see the Namespaced tab.
Usage
"use client";
import * as React from "react";
import { DateTimePicker } from "@/components/ui/datetime-picker";
import { Field } from "@/components/ui/field";
export function ScheduleCall() {
const [at, setAt] = React.useState<Date | null>(null);
return (
<Field label="Call time">
<DateTimePicker value={at} onValueChange={setAt} hourCycle={12} minuteStep={15} timezone="Europe/London" clearable />
</Field>
);

Props
Read from the component’s own TypeScript interface when the site is built, so this table cannot drift from the file you install.
