That is correct, departure and arrival times are off/on-blocks and not airborne or landing.
At one operator I worked for the cabin crew got in to the habit of asking for the slot time which might have been 15 minutes after scheduled departure, the majority of them didn't understand the significance, they would think that the flight had a 15 minute delay so would drag their heels only to realise their mistake at the last minute.
A local airline where I am now, no sooner have the wheels touched the runway surface than the cabin crew are announcing that we have arrived X number of minutes ahead of schedule ... We're still in the middle of an airfield, we haven't arrived yet!
