Fomatting Date returned in Json Response

If the field includes the date and time, the field type is 'timestamp', otherwise it's 'date'.

So you could add:

{% elif field['type'] == 'timestamp' -%}
<td>{{ record[field['id'] | string]['value'] | date_mdy }}</td>

If you want a low tech low solution, just make a table with a record in it and include an embedded report of your report.

Then have a Pipeline update the record on a schedule to trigger an email notification.

But I think this will only work if the users have access to the app because if there are a lot of records on the report it will get truncated in the email if the report is too long.  

I just thought of another route that my work for my needs.  If I create a date formula field to format the timestamp data to a simple date, then use the formula field with to export into my email report.  Instead of trying to format the data from inside the pipeline (outlook channel). - just may work!
