Timesheet time calculation is wrong

Hi,
in timesheet table, work hours calculation is wrong/bugged.
Eg. From 17 to 18(5 to 6 pm) it displays its 0.33 working hours.
ERPNext v12.20. How to fix it?

Please check the standard working hours in company default settings. Make it zero and it may solve the issue.

Hi,
thanks for answer. That solved the problem.
More interesting is that problem exists from V10 or V11 and it’s not fixed yet.
