[Closed] last render time on a local machine?

Hi Guys,

I am using a render callback to save an image after is rendered locally and and also some information about it. There are 3 items I couldn’t find in the help:

1 - Last render time
2 - The render preset used for the render
3 - The viewport rendered

All this information is visible in the render dialog but I couldn’t figure out how to get at it.

I hope I’ve explained good enough what I’m trying to achieve.
Any help is greatly apreciated.
Thanks!
