Hey! I’m currently setting up a job board and pulling schema through HubDB. Everything works well enough but I’d like to setup the ValidThrough property to automatically generate 30 days from DatePosted which is setup as followed:

`"datePosted" : "{{dynamic_page_hubdb_row.job_date_for_schema|datetimeformat('%m/%d/%Y')}}",`

I would like to avoid adding more columns to my HubDB if at all possible.

Is this possible with HubL?

Hey @RockyP ,  
You could use the plus\_time filter to add 30 days to the posted date.
