Not really, lol. I', completely new to Twig.

Here's what I tried-- and it doesn't work.

{% set var1 = field_cp1_time_out_1|date("H:i:s") %}
{% set var2 = field_cp1_time_in_1|date("H:i:s") %}

{% set difference = date(var1).diff(date(var2)) %}

{{ difference }}

I strongly suggest you ask at https://drupal.stackexchange.com/.

I urge you to use the better support resources.

Sorry: I didn't mean to just close this and I added a webform queue triage message although this is in Drupal Core! I've removed that. But the bottom line is that the Drupal Core issue queue is not ideal for support requests because they usually go unanswered here.

Version: 9.3.x-dev » 9.4.x-dev

Drupal 9.3.15 was released on June 1st, 2022 and is the final full bugfix release for the Drupal 9.3.x series. Drupal 9.3.x will not receive any further development aside from security fixes. Drupal 9 bug reports should be targeted for the 9.4.x-dev branch from now on, and new development or disruptive changes should be targeted for the 9.5.x-dev branch. For more information see the Drupal core minor version schedule and the Allowed changes during the Drupal core release cycle.

Same problem using diff produces the following error

Calling "diff" method on a "DateTime" object is not allowed in
