Welcome to the community. Please show your blocks or export your AIA file by going to Projects > Export project (aia) to my computer, because you have not provided a lot of information:

  • the unit of the elapsed time (minutes? seconds?)

  • the format of the "times" (e.g. DD-MM-YY hh:mm:ss)

We need to know your ListPicker's structure, even if you do not have blocks.

Delete from what? What is the purpose/goal?

I have a listpicker with times (e.g. 9:00, 9:30, 10:00, etc.) I would like to compare them with the current time and delete the oldest ones (e.g. it is 9:32 I want to delete them from listpicker elements 9:00 and 9:30).

When? After selecting ...?

As I said, describe exactly the goal of your app or this procedure.

I don't understand your example. Please express it clearly and give us a comprehensible example or better two.

Here is a post that answers a similar question, at the date level.

You might be able to build on that.
