On the "Current job" screen in the Route Advisor, the expected delivery time is always given as a range, e.g. "Fri 21:50 - Sat 2:00".
Why is that? I know the second time is the actual deadline and if you miss it, you fail the job, but what's the purpose of the first time? Is there a bonus (or penalty) for delivering the cargo early?
I thought this was simply cosmetic, but I've noticed that high-priority delivery jobs tend to have a narrower time window, which I assume is meant to make the job more challenging, but in what way exactly?
