/**
 * This workaround prevents a bug existing in the NativeAndroid variant.
 * The bug displays duplicated "12" hours string when the current time is set to "1".
 * Haven't found the root cause of this bug but since this bug only occurs in the NativeAndroid
 * variant there are reasons to believe there is a internal bug in Android's NumberPicker for this
 * use case.
 *
 * More info about the bug:
 * https://github.com/henninghall/react-native-date-picker/issues/382
