#83 Gap of multiple of 5 days leads to wrong start date

[Eric L.]

Steps to reproduce:

1. create a task 1 ending on a Friday at 17h00 (standard end of the day)
2. create a task 2 of 1 day depending on task A with a gap of 5 days or a multiple (e.g. 1FS+5days)
3. then you'll see that task 2 starts on Saturday 8h00 and ends on Monday 17h00.

Conclusion:

End time is correct, but start time is obviously wrong, it should be Monday 8h00.
