Insert date and time stamp when adding notes

I would like to have a date and time stamp added to the notes I enter for a task. This could be a manual action, via an “add date/time stamp” button or an automatic inserted one.

Thanks.

Pascal.

Here is a similar discussion about time stamps in the notes/comments: http://forum.gtdnext.com/t/progress-notes-journal

And here is a discussion about time stamps for the tasks as such (a “since” date or “historic start date”): http://forum.gtdnext.com/t/since-date-in-next-waiting-someday
