Just tested this on my post: editing it doesn't seem to invalidate the existing timestamp.
That kind of defeats the point of OTS right?Everyone can just edit their notes with hindsight while the client is erroneously showing a timestamp proof for the original.
It would be nice if @Vitor Pamplona can clarify how timestamping works. But my guess is that it is linked to a note not edit. It would be better if one could timestamp each individual edit as separate notes and as one switches between edits one can see if they are timestamped or not.
Good catch! I will fix it
