Hi,
You are on the right track.
1) Specify the data type as Numerical and the Modeling type as Continuous
2) Set the desired appearance format as Time (e.g., m/d/y h:m:s)
3) Check that the Input Format is set to m/d/y h:m:s
Although the dates will appear in a formatted string (see step 2), you will be able to calculate differences using the "date_difference" formula and plot these values as a genuine time scale.
Note: however, if you want the raw time/date code, simply change step 2 to Best Fit
Best,
