"The Legend". Problems with the walkthrough.

There is a way to shorten this time.
1. If you set sail in the morning, you will arrive during the day of the same date.

I'm currently playing version 1.6.0, and I've noticed that if you fly or sail before 7:00 AM, you arrive at your destination at exactly 7:00 AM on the same day.
At least, that's how it was for me: I set off around 2:00 AM and arrived at 7:00 AM on the same day. However, when I was doing the "Indulgence" quest, I sailed from the islands around 9:30-10:00 AM and arrived in Darion at 7:00 AM the next day (significant time loss).
