My bad, you're right. Tim wrote about this in the past here: [Kibana Filter for a specific time range](https://discuss.elastic.co/t/kibana-filter-for-a-specific-time-range/105169/2)

You would have to extract that into something that is filterable, like a boolean field "is\_working\_hours". You could use a scripted field, but that wouldn't be very performant.
