Let's hypothetically say that on someone's screen, for some random song, the correct offset is 1535. Now, I open up that song in the editor, and 1535 is completely wrong on my screen. Like, in the range of 60 off the mark. It's a very noticeable difference. Now, I have complete confidence that on the other person's screen, 1535 is the correct offset (in this example, the person is a BAT). I also know that on my screen, 1475 is the correct offset. What's the reason for this difference, and how can I correct it when trying to discuss the timing of a map with someone?
