The default footer in Divi breaks my workflow. I typically use php to echo the copyright and date in wp_footer() within the childtheme. Within Divi the workflow changes, especially if you’re trying to stay away from the need to create child themes. This is a simple but “elegant” workaround. 😉
Divi > Theme Options > Integrations > Add code to the <body> (save)
<script>document.getElementById("year").innerHTML = new Date().getFullYear();
</script>
Appearance > Customize > Footer > Bottom Bar > Edit Footer Credits (publish)
