Seems to me some people don't get what a time sink is. A time sink in a game is a mechanic where you have to sink time into it.
A grind for credits or reputation.
Farming a dungeon for specific loot.
Being forced to repeat the same activity over and over to finally - mostly depending on luck - you might by chance achieve your goal.
Delayed ship transport is none of this. You look up the specific option in the station menu, click it, and are freed of any further time investment or responsibility for the transport. You can log off, you can keep playing, you can simply sit on your butt doing nothing, if you prefer to. Basically you are totally free to do whatever you want and are not obligated to spend another second on the ship delivery.
You know what a time sink is instead? Having to spend ours flying around the galaxy doing all the fetching yourself.
Not disagreeing here, but curious about one point.
Do we know that it works when logged off ?
