Problem with date_query_after and before

Hello

I use in shortcodes date_query_after:

[display-posts post_type=”event_listing” s=”Tartempion” orderby=”event_start_date” date_query_after=”today”]

But it doesn’t work ! Same for the date_query_before !
Is it because the date_query_xxx item uses only the modification date ? or publication date ?

thx a lot for your help
