Incrementing Date field in Variable based on a specific calendar

Question

Hello All,
    I am currently setting up a schedule that includes Mass activities. I am running into a problem when i want a particular date field an activity to increment by one day based on a specific calendar i.e. Factory calendar (M-F open).
EX)
The due date field for on any given day the mass activity runs should be system date plus 2 business days.
While the posting date field on the same transaction should increment by 2 day.
Result would be:
On System date = 02/17/11
Due Date Field = 02/21/11
Posting Date = 02/19/11
I am currently using expression similiar to this: =Time.expression(Time.now('GMT'), 'add 2 days') but cannot find documentation how to include calendars in this as you would with =Time.isTimeWindowOpen(Time.now('GMT'), 'Factory Calendar').
Can someone please point me in right direction?
Thanks
Dan

Hi Gerben,
   I tried this and it yielded unacceptable(expected) results. Here is why i think this is the case.
=Time.expression(Time.nextTimeWindowOpening(Time.now('America/Regina'), 'System_Week_WorkDays'), 'add 7 days') suppose to only be open m-f
Time.now() should evaluate to today lets say 02/21/11
then Time.nextTimeWindowOpening should return the next open day, after but including today, it checks and finds today is open so = 02/21/11
and the time expression will add n= 7 days to that. 02/21/11 + 7 = 02/28/11 this is wrong.
According to this calendar it should be 03/01/11
Problem is that the add function is just adding n days indiscriminate of the calendar as the calendar is not part of the addition argument.
