Time Feature Preprocessing

[IraWatt]

Hello,

I'm trying to recreate the formula from my Eureqa model (shown below). I'm not sure how the model is able to minus/times the time variables 'GAME_CLOCK'. How does DataRobot convert time variables to perform numeric calculations on them?  

Here is my models blueprints (neither Numeric nor categorical transformations mention time):

Eureqa Formula:

GAME_CLOCK feature:

@IraWatt I had a question about a term preceded by "-*". Do you know what that notation means?

Hey Ira! Have you checked out these doc pages?

https://docs.datarobot.com/en/docs/modeling/time/ts-reference/feature-eng.html

https://docs.datarobot.com/en/docs/data/transform-data/transform-primary-datasets/auto-transform.htm...

Maybe they have more info to explain this?

I agree It most likely is a converts the time format to a number. Though its not clear how, unless I did the maths wrong nether converting to seconds or milliseconds gets you near predicted result using the formula.

Look at the format of your date time. DR may be reading your date inputs as numeric
