How to Convert DateTime 30-Jun-2002 12:00:00 AM to Double?

Question

Hi all,

 

 I am trying to retrieve data from MySql db. The one column is DateTime type 12-Jun-90 12:00:00 AM and the other column is type double Price(15.00).

 

Could you please tell me how to Convert the DateTime to double in order to perform some stastistical calculations and visualisation with R.NET?

 

R.NET requires only Numerical vectors
