Did you try the calculation below:
I am able to get 530 minutes. Please find the workbook attached.
Thanks for your answer.
Unfortunately I cannot open your workbook, cuz I've an older version. I
will update soon.
Yes I did use that formula, the same way. What I think is the problem, is
that I just inserted times, no dates. Therefore, I guess tableau does not
know they are different days after midnight.
Are you using dates in your workbook?

Yes, I am using Dates.
Another way to look at it:
DATEDIFF('minute',DATETIME("May 26, 2018 5:40:00 PM"),DATETIME("May 27, 2018 2:30:00 AM"))
