<DateTime>

Overview

The <DateTime> component renders a formatted date or time string, supporting customization such as formatting options and locale. The date or time is formatted according to the current locale and any optional parameters passed.

Examples

Basic usage

The <DateTime> component can be used to display localized date or time values.

EventDate.jsx

import { DateTime } from 'gt-next';

export default function EventDate(event) {
    return (
        <DateTime> {event.date} </DateTime>. 
    );
}

Specifying locales

The <DateTime> component can be used to display date or time values in a specific locale.

EventDate.jsx


import { DateTime } from 'gt-next';

export default function EventDate(event) {
    return (
        <DateTime locales={['fr-FR']}> {event.date} </DateTime>. 
    );
}

Translating `<DateTime>`

Say that you want the datetime to be displayed in a sentence that is also being translated. You can wrap the <DateTime> component in a <T> component.

EventDate.jsx

import { T, DateTime } from 'gt-next';

export default function EventDate(event) {
    return (
        <T id="eventDate">
            The time of the event is <DateTime> {event.date} </DateTime>. // [!code highlight]
        </T>
    );
}

Custom formatting

The <DateTime> component supports custom formatting options.

EventDate.jsx

import { DateTime } from 'gt-next';

export default function EventDate(event) {
    return (
        <DateTime options={{
            dateStyle: 'full', 
            timeStyle: 'long', 
            timeZone: 'Australia/Sydney', 
        }}>
            {event.date}
        </DateTime>.
    );
}
