<TimeField label="Event time" />

Value#

A TimeField displays a placeholder value by default. An initial, uncontrolled value can be provided to the TimeField using the defaultValue prop. Alternatively, a controlled value can be provided using the value prop.

Time values are provided using objects in the @internationalized/date package. This library handles correct international date and time manipulation across calendars, time zones, and other localization concerns.

TimeField only supports selecting times, but values with date components are also accepted. By default, TimeField will emit Time objects in the onChange event, but if a CalendarDateTime or ZonedDateTime object is passed as the value or defaultValue, values of that type will be emitted, changing only the time and preserving the date components.

import {Time} from '@internationalized/date';

function Example() {
  let [value, setValue] = React.useState(new Time(11, 45));

  return (
    <Flex gap="size-150" wrap>
      <TimeField
        label="Time (uncontrolled)"
        defaultValue={new Time(11, 45)} />
      <TimeField
        label="Time (controlled)"
        value={value}
        onChange={setValue} />
    </Flex>
  );
}

import {Time} from '@internationalized/date';

function Example() {
  let [value, setValue] = React.useState(new Time(11, 45));

  return (
    <Flex gap="size-150" wrap>
      <TimeField
        label="Time (uncontrolled)"
        defaultValue={new Time(11, 45)} />
      <TimeField
        label="Time (controlled)"
        value={value}
        onChange={setValue} />
    </Flex>
  );
}

import {Time} from '@internationalized/date';

function Example() {
  let [value, setValue] =
    React.useState(
      new Time(11, 45)
    );

  return (
    <Flex
      gap="size-150"
      wrap
    >
      <TimeField
        label="Time (uncontrolled)"
        defaultValue={new Time(
          11,
          45
        )}
      />
      <TimeField
        label="Time (controlled)"
        value={value}
        onChange={setValue}
      />
    </Flex>
  );
}

Time values may also be parsed from strings using the parseTime function. This accepts ISO 8601 formatted time strings such as "04:45:23.123". The toString method of a Time object can also be used to convert a time object to a string.

Time zones#

TimeField is time zone aware when a ZonedDateTime object is provided as the value. In this case, the time zone abbreviation is displayed, and time zone concerns such as daylight saving time are taken into account when the value is manipulated.

In most cases, your data will come from and be sent to a server as an ISO 8601 formatted string. @internationalized/date includes functions for parsing strings in multiple formats into ZonedDateTime objects. Which format you use will depend on what information you need to store.

parseZonedDateTime – This function parses a date with an explicit time zone and optional UTC offset attached (e.g. "2021-11-07T00:45[America/Los_Angeles]" or "2021-11-07T00:45-07:00[America/Los_Angeles]"). This format preserves the maximum amount of information. If the exact local time and time zone that a user selected is important, use this format. Storing the time zone and offset that was selected rather than converting to UTC ensures that the local time is correct regardless of daylight saving rule changes (e.g. if a locale abolishes DST). Examples where this applies include calendar events, reminders, and other times that occur in a particular location.
parseAbsolute – This function parses an absolute date and time that occurs at the same instant at all locations on Earth. It can be represented in UTC (e.g. "2021-11-07T07:45:00Z"), or stored with a particular offset (e.g. "2021-11-07T07:45:00-07:00"). A time zone identifier, e.g. America/Los_Angeles, must be passed, and the result will be converted into that time zone. Absolute times are the best way to represent events that occurred in the past, or future events where an exact time is needed, regardless of time zone.
parseAbsoluteToLocal – This function parses an absolute date and time into the current user's local time zone. It is a shortcut for parseAbsolute, and accepts the same formats.

import {parseZonedDateTime} from '@internationalized/date';

<TimeField
  label="Event time"
  defaultValue={parseZonedDateTime('2022-11-07T00:45[America/Los_Angeles]')}
/>

import {parseZonedDateTime} from '@internationalized/date';

<TimeField
  label="Event time"
  defaultValue={parseZonedDateTime(
    '2022-11-07T00:45[America/Los_Angeles]'
  )}
/>

import {parseZonedDateTime} from '@internationalized/date';

<TimeField
  label="Event time"
  defaultValue={parseZonedDateTime(
    '2022-11-07T00:45[America/Los_Angeles]'
  )}
/>

TimeField displays times in the time zone included in the ZoneDateTime object. The above example is always displayed in Pacific Standard Time because the America/Los_Angeles time zone identifier is provided. @internationalized/date includes functions for converting dates between time zones, or parsing a date directly into a specific time zone or the user's local time zone, as shown below.

import {parseAbsoluteToLocal} from '@internationalized/date';

<TimeField
  label="Event time"
  defaultValue={parseAbsoluteToLocal('2021-11-07T07:45:00Z')}
/>

import {parseAbsoluteToLocal} from '@internationalized/date';

<TimeField
  label="Event time"
  defaultValue={parseAbsoluteToLocal(
    '2021-11-07T07:45:00Z'
  )}
/>

import {parseAbsoluteToLocal} from '@internationalized/date';

<TimeField
  label="Event time"
  defaultValue={parseAbsoluteToLocal(
    '2021-11-07T07:45:00Z'
  )}
/>

Granularity#

The granularity prop allows you to control the smallest unit that is displayed by a TimeField. By default, times are displayed with "minute" granularity. More granular time values can be displayed by setting the granularity prop to "second".

<TimeField
  label="Event time"
  granularity="second"
  defaultValue={parseAbsoluteToLocal('2021-04-07T18:45:22Z')} />

<TimeField
  label="Event time"
  granularity="second"
  defaultValue={parseAbsoluteToLocal(
    '2021-04-07T18:45:22Z'
  )}
/>

<TimeField
  label="Event time"
  granularity="second"
  defaultValue={parseAbsoluteToLocal(
    '2021-04-07T18:45:22Z'
  )}
/>

Labeling#

A visual label should be provided for the TimeField using the label prop. If the TimeField is required, the isRequired and necessityIndicator props can be used to show a required state.

<Flex gap="size-150" wrap>
  <TimeField label="Event time" />
  <TimeField label="Event time" isRequired necessityIndicator="icon" />
  <TimeField label="Event time" isRequired necessityIndicator="label" />
  <TimeField label="Event time" necessityIndicator="label" />
</Flex>

<Flex gap="size-150" wrap>
  <TimeField label="Event time" />
  <TimeField
    label="Event time"
    isRequired
    necessityIndicator="icon"
  />
  <TimeField
    label="Event time"
    isRequired
    necessityIndicator="label"
  />
  <TimeField
    label="Event time"
    necessityIndicator="label"
  />
</Flex>

<Flex
  gap="size-150"
  wrap
>
  <TimeField label="Event time" />
  <TimeField
    label="Event time"
    isRequired
    necessityIndicator="icon"
  />
  <TimeField
    label="Event time"
    isRequired
    necessityIndicator="label"
  />
  <TimeField
    label="Event time"
    necessityIndicator="label"
  />
</Flex>

Accessibility#

If a visible label isn't specified, an aria-label must be provided to the TimeField for accessibility. If the field is labeled by a separate element, an aria-labelledby prop must be provided using the id of the labeling element instead.

Internationalization#

In order to internationalize a TimeField, a localized string should be passed to the label or aria-label prop. When the necessityIndicator prop is set to "label", a localized string will be provided for "(required)" or "(optional)" automatically.

Events#

TimeField accepts an onChange prop which is triggered whenever the time is edited by the user. The example below uses onChange to update a separate element with a formatted version of the date in the user's locale and local time zone. This is done by converting the date to a native JavaScript Date object to pass to the formatter. The TimeField allows editing the time components while keeping the date fixed.

import {getLocalTimeZone} from '@internationalized/date';
import {useDateFormatter} from '@adobe/react-spectrum';

function Example() {
  let [date, setDate] = React.useState(
    parseAbsoluteToLocal('2021-04-07T18:45:22Z')
  );
  let formatter = useDateFormatter({ dateStyle: 'long', timeStyle: 'long' });

  return (
    <>
      <TimeField label="Time" value={date} onChange={setDate} />
      <p>
        Selected date and time:{' '}
        {formatter.format(date.toDate(getLocalTimeZone()))}
      </p>
    </>
  );
}

import {getLocalTimeZone} from '@internationalized/date';
import {useDateFormatter} from '@adobe/react-spectrum';

function Example() {
  let [date, setDate] = React.useState(
    parseAbsoluteToLocal('2021-04-07T18:45:22Z')
  );
  let formatter = useDateFormatter({
    dateStyle: 'long',
    timeStyle: 'long'
  });

  return (
    <>
      <TimeField
        label="Time"
        value={date}
        onChange={setDate}
      />
      <p>
        Selected date and time:{' '}
        {formatter.format(date.toDate(getLocalTimeZone()))}
      </p>
    </>
  );
}

import {getLocalTimeZone} from '@internationalized/date';
import {useDateFormatter} from '@adobe/react-spectrum';

function Example() {
  let [date, setDate] =
    React.useState(
      parseAbsoluteToLocal(
        '2021-04-07T18:45:22Z'
      )
    );
  let formatter =
    useDateFormatter({
      dateStyle: 'long',
      timeStyle: 'long'
    });

  return (
    <>
      <TimeField
        label="Time"
        value={date}
        onChange={setDate}
      />
      <p>
        Selected date and
        time:{' '}
        {formatter
          .format(
            date.toDate(
              getLocalTimeZone()
            )
          )}
      </p>
    </>
  );
}

Validation#

TimeField can display a validation state to communicate to the user whether the current value is valid or invalid. Implement your own validation logic in your app and pass either "valid" or "invalid" via the validationState prop. The errorMessage prop can be used to communicate errors to the user.

This example validates that the selected time is on a 15 minute increment.

function Example() {
  let [time, setTime] = React.useState(new Time(9, 15));

  return (
    <TimeField
      label="Meeting time"
      value={time}
      onChange={setTime}
      validationState={time.minute % 15 ? 'invalid' : 'valid'}
      description="Select a meeting time"
      errorMessage="Meetings start every 15 minutes." />
  );
}

function Example() {
  let [time, setTime] = React.useState(new Time(9, 15));

  return (
    <TimeField
      label="Meeting time"
      value={time}
      onChange={setTime}
      validationState={time.minute % 15
        ? 'invalid'
        : 'valid'}
      description="Select a meeting time"
      errorMessage="Meetings start every 15 minutes."
    />
  );
}

function Example() {
  let [time, setTime] =
    React.useState(
      new Time(9, 15)
    );

  return (
    <TimeField
      label="Meeting time"
      value={time}
      onChange={setTime}
      validationState={time
          .minute % 15
        ? 'invalid'
        : 'valid'}
      description="Select a meeting time"
      errorMessage="Meetings start every 15 minutes."
    />
  );
}

Minimum and maximum values#

The minValue and maxValue props can also be used to perform builtin validation. This displays an invalid state if the user enters an invalid time into the time field.

This example only accepts times between 9 AM and 5 PM.

<TimeField
  label="Meeting time"
  minValue={new Time(9)}
  maxValue={new Time(17)}
  defaultValue={new Time(8)} />

<TimeField
  label="Meeting time"
  minValue={new Time(9)}
  maxValue={new Time(17)}
  defaultValue={new Time(8)} />

<TimeField
  label="Meeting time"
  minValue={new Time(
    9
  )}
  maxValue={new Time(
    17
  )}
  defaultValue={new Time(
    8
  )}
/>

Visual options#

Quiet#

<TimeField label="Event time" isQuiet />

<TimeField label="Event time" isQuiet />

<TimeField
  label="Event time"
  isQuiet
/>

Disabled#

<TimeField label="Event time" isDisabled />

<TimeField label="Event time" isDisabled />

<TimeField
  label="Event time"
  isDisabled
/>

Read only#

The isReadOnly boolean prop makes the TimeField's value immutable. Unlike isDisabled, the TimeField remains focusable.

<TimeField label="Event time" value={new Time(11)} isReadOnly />

<TimeField
  label="Event time"
  value={new Time(11)}
  isReadOnly
/>

<TimeField
  label="Event time"
  value={new Time(11)}
  isReadOnly
/>

Label alignment and position#

View guidelines

By default, the label is positioned above the TimeField. The labelPosition prop can be used to position the label to the side. The labelAlign prop can be used to align the label as "start" or "end". For left-to-right (LTR) languages, "start" refers to the left most edge of the TimeField and "end" refers to the right most edge. For right-to-left (RTL) languages, this is flipped.

<TimeField label="Event time" labelPosition="side" labelAlign="end" />

<TimeField
  label="Event time"
  labelPosition="side"
  labelAlign="end"
/>

<TimeField
  label="Event time"
  labelPosition="side"
  labelAlign="end"
/>

Help text#

View guidelines

Both a description and an error message can be supplied to a TimeField. The description is always visible unless the validationState is “invalid” and an error message is provided. The error message can be used to help the user fix their input quickly and should be specific to the detected error. All strings should be localized. See the Validation section above for an example.

Placeholder value#

When no value is set, a placeholder value is shown. By default, this is midnight. However, this can be overridden by setting the placeholderValue prop to a more appropriate placeholder for your specific usecase.

<TimeField label="Appointment time" placeholderValue={new Time(9)} />

<TimeField
  label="Appointment time"
  placeholderValue={new Time(9)}
/>

<TimeField
  label="Appointment time"
  placeholderValue={new Time(
    9
  )}
/>

Hide time zone#

When a ZonedDateTime object is provided as the value of a TimeField, the time zone abbreviation is displayed by default. However, if this is displayed elsewhere or implicit based on the usecase, it can be hidden using the hideTimeZone option.

<TimeField
  label="Appointment time"
  defaultValue={parseZonedDateTime('2022-11-07T10:45[America/Los_Angeles]')}
  hideTimeZone />

<TimeField
  label="Appointment time"
  defaultValue={parseZonedDateTime(
    '2022-11-07T10:45[America/Los_Angeles]'
  )}
  hideTimeZone
/>

<TimeField
  label="Appointment time"
  defaultValue={parseZonedDateTime(
    '2022-11-07T10:45[America/Los_Angeles]'
  )}
  hideTimeZone
/>

Hour cycle#

By default, TimeField displays times in either 12 or 24 hour hour format depending on the user's locale. However, this can be overridden using the hourCycle prop if needed for a specific usecase. This example forces the TimeField to use 24-hour time, regardless of the locale.

<TimeField
  label="Appointment time"
  hourCycle={24} />

<TimeField
  label="Appointment time"
  hourCycle={24} />

<TimeField
  label="Appointment time"
  hourCycle={24}
/>

A Time represents a clock time without any date components.
