import { HourFormat } from 'react-native-hour-format';
HourFormat.is24HourFormat() // bool
HourFormat.getHourFormat() // 12 or 24
HourFormat.getLocale() // string with system localeUse 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'
}
