A way to make pdfpc display current date, or fields.

The feature wish description:

Hi, I haven't used Vala before, so I do not know if it is possible with the way pdfpc rendering is structured. But I think this would be a nice feature. And I want to discuss it before I try to attempt it (or maybe someone else can also try, or have already tried).

And if it can be done from PDF side (maybe through forms or other tags) and pdfpc just support the insertion of current date, then that'd also work.

Otherwise, would it be possible to create something that'll always display current date/time? For example, we can have a command on the LaTeX package to insert it, and for PDF compilation, it'll compile with certain extra information as well as the placeholder date+time while compiling. And in normal cases it would fall back to it, but pdfpc can detect it and display current datetime.

I see it being useful while presenting PDF compiled from previous days without having to insert the date manually, as I start with \today in the date field.

And as cherry on top. I was thinking if we could even make "fields" and have the key=value for the fields in the .pdfpc file, so we can easily change those things and reuse the presentation for different purposes.
