Duration and Schedules: Question

Hi all:

Hopefully a simple one, but I wanted to vet it with the community experts.

We are starting to dabble in planned hours for teams in Workfront, which I support. As part of this, we are also looking at the work schedules, which default to 8 hours. We actually do a 7-hour workday, so the ask was to make the schedule 7 hours so the planned hours are more aligned with our actual experience. Makes sense to do so, but I'm trying to see if there's a ripple effect I can't predict.

My asks is if moving the calendar from an 8-hour work day to a 7-hour one...

• For a task with a duration of say 1.5 days, Is Workfront smart enough to say "this equates to halfway through the following workday" regardless of what said workday is? 
• Or put another way, would a project schedule with a 8.5 day project planned duration still dynamically calculate 8.5 days out from actual project start date?

My guess is the answer is "yes" but I wanted to validate with those that have changed their schedules and seen the impact.

Thanks,

Ryan
