Hi @vstefano ,
the values “time” for the starting and end point are the variables you are looking for… just in the wrong format.
Both are in the UNIX format (1970-01-01 is 0), meaning that if you want to use variables in your data generation node, you’ll need to convert your dates variables in the UNIX format. To do it, you can use a Date&Time difference node as described in this post.
Here is a small workflow to show what I’ve done, hope it helps.
Have a nice evening,
Raffaello Barri
