How to pivot a table on datetimes as values?

[alespooletto]

I was able to create this pivot table with the desired values as columns, but the problem is with the values. I want to show DateTimes as values under these columns, but how can i do so?

Thank you @vincent_ardiet_ , I tried to do that but it seems they aren't ordered:

Should I sort by another dimension?

Sorting pivot table is always painful. And you have also NULL cells (according to your first screenshot) and this is not helping.

Yes, indeed there are some NULLs which I am dealing with in the Load Editor.
