Looking for Date/Time Field 1 = Date/Time Field 2 pipeline jinja

I begin with one trigger step and in the next step I need to filter records to match date time fields in both tables.

My workaround is the native "is on date" filter but it would be best if I could include the timestamp portions of the field. Is there a way to format jinja to accomplish this? 

I've tried several variations but here is an example of one. 

{% if a.pull_date == b.pull_date %}

{{"TRUE"}}

{% else %}

{{"FALSE"}}

{% endif %}
