Is there a secret created or modified value for the signature field?

I see this in the activity log if I change the drawn signature:


Is there a doc.my_signature_field.created type of hidden field that I can read? that would be awesome if so

It’s not a hidden field. The image in saved/read as an base64 image string. That’s what you’re seeing on the screen.

oh sorry yes I understood that. I am just wondering if there is also another field created somewhere that associates timestamp with that field. I suppose activity log has it if nothing else.

There’s a doctype called Version which tracks/logs all the revisions/changes that’s made.

Additionally each doctype has a field called modified that tracks the timestamp of the last modification made.
