The clock end is earlier than the start because it belongs to the next calendar day. That fact must be selected, not inferred silently.
Enter 22:00, 06:00, and next day
Create one row, set the start to 22:00 and end to 06:00, then select that the shift ends the next day. Enter 30 whole break minutes.
The gross duration is 8:00
Two hours remain before midnight and six follow after midnight. The combined gross duration is 480 minutes. Equal start and end with next day would instead represent an explicit 24-hour shift.
The worked result is 7:30
Subtracting the 30-minute break leaves 450 worked minutes, formatted as 7:30 and 7.50 decimal hours. Any night premium, overtime threshold, or required break remains outside this arithmetic result.
