Hi

I would like to ask how may I use the entity extraction for the date and time by using the DIETClessifier?

for example, how I can do it for this intent?

- intent: flight_search_intent

    - I am looking for a [flight](Search_flight) from [Dammam](city) to [Riyadh](city) Tomorrow
    - I want to book a [flight](Search_flight) from [Dammam](city) to [Riyadh](city) Tomorrow
    - I want to book a [flight](Search_flight) from [Dammam](city) to [Riyadh](city) Tomorrow asap
    - Can you please find a [flight](Search_flight) for me from [Dammam](city) to [Riyadh](city) Tomorrow
    - I want to book a [ticket](Search_flight) from [Dammam](city) to [Riyadh](city)
    - Book a [flight](Search_flight) from [Dammam](city) to [Riyadh](city) Tomorrow
