Yo. Faced the same issue but setting the locale property solved it, I.e:

          <TimePicker
            is24Hour={true}
            mode="time"
            locale="en-FR"
            minuteInterval={15}
            testID="dateTimePicker"
            value={timeOfMeal}
            display="inline"
            onChange={changeTime}
          />
