Lack of interest Use XF templates to display custom thread field

[Don Daniello]

The custom thread field currently has Value display HTML option, documented as:

If not empty, this allows you to format the value of this field using HTML, allowing you to do things like link or mark up the output. You may use these placeholders: {$value} - the field's display value; {$valueUrl} - the field's display value for use in a URL, {$choice} - the underlying value of the chosen option, and {$fieldId} - the ID of this field (test_field).

What I'd like to achieve is to format the display like this:

<xf:date time="{$value}" />

This currently does not seem possible (or I simply don't know how to use this).
