Make time using event offsets in sql or excel

Shift and events
Above is an image of a table containing events occuing during a shift. I have a start time and an end time for the shift but I am trying to convert the fields "StartOffset" and "StopOffset" into time. I've used some contacts along with the floor function to create time but that off set represented minutes from midnight (0 = 12:00:00 AM). I thought I could maybe use the same approach but instead using the ShiftStartTime as my floored time. Didnt work. Any assistance with this would be much appreciated.

If this is one-time then you can follow the following steps.

Enter a value 1440 in any blank cell
Select the cell
Ctrl-c
select the start and stop data (without headers)
paste-special with "Divide" option
OK
Select shift start data (without headers)
Ctrl-c
select the start and stop data (without headers)
paste-special with "Add" option
OK

The same has been programmed in a macro.

Sub timeoffsets()
Dim cel As Range, tgt As Range
Set cel = ActiveSheet.Cells.SpecialCells(xlCellTypeBlanks).Cells(1, 1)
cel.Value = 1440
cel.Copy
Set tgt = ActiveSheet.Range("D2:E" & ActiveSheet.Range("D2").End(xlDown).Row)
tgt.PasteSpecial , operation:=xlPasteSpecialOperationDivide
ActiveSheet.Cells.SpecialCells(xlCellTypeBlanks).Cells(1, 1).Select
cel.ClearContents
tgt.Offset(, -2).Resize(, 1).Copy
tgt.PasteSpecial , operation:=xlPasteSpecialOperationAdd
End Sub
