Problem with service profile (diff. time)

Hi all!

Help me please with problem.

By SLA our working hours on Friday are from 09:00 to 16:45, from Monday to Thursday are from 09:00 to 18:00.  In service profile we have made settings:

It works fine, but last Friday was a holiday (calendar is active on 2015, settings are correct). In many incidents SLA was calculated without this holiday. I repeated this problem in SM0. If I change working hours for Friday to 09:00-18:00, SLA will work fine.

For example (the same settings in response profile – 12 hours for very high priority; different settings for working hours)

:

*2614 - Friday  09:00-16:45

*2613 - Friday  09:00-18:00
