Getting temp for a specific hour with the Timeline API

I'm attempting to use the timeline API to get weather data at a specific hour of the day for a day in the past like this:

https://weather.visualcrossing.com/VisualCrossingWebServices/rest/services/timeline/10025/2016-07-03T15:00:00?unitGroup=us&elements=tempmax%2Cdew%2Ctemp%2Cfeelslike&key=KEY&contentType=json&include=current

That is working fine, however the temp doesn't appear accurate.  If I get hourly data for the whole day, I would expect the temp from the query above to match what I find at the 15:00 hour in the full days worth of data, but it doesn't:

The hourly data for the whole day better reflects what I would expect to see, however, I just want to query for a single hour in the day.

After playing around with it a little, it seems that the temp returned in the first query (for 1 specific hour of the day) is always the "feelslike" temp and not the regular "temp" that I see for the same hour (15:00) in hourly data for that day.

Am I misunderstanding what the "temp" query parameter is returning?  If so, how can I get the actual temp for a specific hour of the day?

  Thank for your question. The specific time request does not affect the days and hours of the response - the day will field will continue to show the high and low temperatures etc for the entire day. 

  When you include a specific time, the results of that time are populated into the 'currentConditions' field. 

  Specific Time Request Example

  The following will retrieve the weather data for London, UK for the 15th December 2020 and will request the current conditions property be populated using the conditions at 13:00 local time (1pm local time).

  https://weather.visualcrossing.com/VisualCrossingWebServices/rest/services/timeline/London,UK/2020-12-15T13:00:00?key=YOUR_API_KEY 

  The above example will include the daily and hourly detail for the day of the current conditions (2020-12-15 in this case). This query cost will therefore be 24. If you only need the specific time data, and don’t need the hourly detail, you can reduce the query costing using the include parameter:
