On the other hand the picker does not accept lower hours than `minTime` and higher than `maxTime`. Manually entered times outside of the defined bounds will be rejected by the picker, no extra validation is therefore needed ([example](https://jannicz.github.io/appointment-picker/example/form-submit.html)).
