I'm building a Google Home skill using Dialogflow. I want the user to be able to say a date time such as "today at 3pm", "Wednesday at 11am", or "August 10 at 5pm."
Dialogflow has several prebuilt entities including: date, time, and date-time. For some reason the system seems to always parse date and time separately instead of just as date-time. I've tried putting in several examples and manually setting the entity type to date-time but whenever I add another one it always parses them separately.
Any ideas how I could force it to extract date-time as one entity?
