In figure 2.2 you maybe have noticed that task1
does not start at January 16th but one day later at 8:00 am. faces
tasks are of course aware of working times and vacations. (more on
that in section 7.1.4) If you specify a start
property outside the working times (January the 16th is a Sunday), it
will be moved to the next valid working time. In contrast the
end property will be moved to the previous valid working
time.
