I want to calculate delay time for any work/process. I have shifts timing table just like office timing and it may be 1st, 2nd, or 3rd shift in a day. In between the timing few minute breaks are there for lunch or tea break etc.
One work/Process may be finished within 1st shift or it may go to 2nd, 3rd shift also or work may go to next day any shift also. And I have a standard time for the work/process to complete.

So I have to calculate the delay time for one work/process.
Case 1 - Support Today there are only two shift. Process1 got started on 2nd shift at 18:30 and StandardTime is 10 Hours to complete the process and suppose it got finished next day 1st shift. So. Calculation would be something like this.
23:35(End of 2nd shift of first day) โ 18:30 (Process starting time) โ00:30 mins (Lunch break) โ 00:10 (mins tea break) = 4:25 mins. Job is done. Next 5:30 mins job will be done on next day 1st shift. Next day calculation would be the same like.
5:55 am + 5:35 (hr job remain) + 30 min (lunch break) + 10 min (tea break). So the work should be finished by 12:00 AM afternoon.
And Holiday also I have to calculate. And I need to add to this holiday to calculate delay.
