It's got to be said: it's a good improvement that one can enter hours/minutes for render quality. This way I don't have to re-calculate each time how much seconds I need from friday 16:00h till monday 08:00h or so.
As I tend to render over the weekend en just let it work as much as it can till I make it back to the office, it be great to be able to say:
"Render till April 3rd 08:00h".
I know I could just start it friday and then when I make it to the office hit "stop". But that don't work for Qed renders, there I need to spread them out equaly.
