There are three methods you can call:

Use below snippet so moment().format('LT') will return correctly formated values.

import { HourFormat } from 'react-native-hour-format';
import moment from 'moment';

const is24HourFormat = HourFormat.is24HourFormat();
moment.updateLocale('en', {
  longDateFormat: {
    LT: is24HourFormat ? 'HH:mm' : 'hh:mm a',
    LTS: is24HourFormat ? 'HH:mm:ss' : 'hh:mm:ss a'
	}
});

react-native-hour-format's Issues

Date format?

Is it possible to get date format from system? Like if it should me month / day / year or day / month / year etc.

RNHourFormat requires main queue setup

Hi,
on iOS in RN 51 console show this warning :

Module RNHourFormat requires main queue setup since it overrides constantsToExport but doesn't implement requiresMainQueueSetup. In a future release React Native will default to initializing all native modules on a background thread unless explicitly opted-out of.

Event listener for change during app running

Is it possible to request please an addEventListener sort of thing to trigger when a change happens during runtime?

HourFormat.getLocale() is null

On Android 6.0 I am getting null for return of HourFormat.getLocale().

broken podspec

arnif@33c63cb fixes the following build error:

node_modules/react-native-hour-format/ios/RNHourFormat.h:8:9: 'React/RCTBridgeModule.h' file not found

...by adding a podspec dependency on React, but puts the podspec in the wrong place. It should be in the top-level directory, not the ios/ directory.

Thanks!

Thanks very much for this module! It was so needed as this one was a bit poor - https://github.com/brentvatne/react-native-device-clock-format
