That is not correct.   It may not be in the Redbook, but it says this in
the Planning: Workload Management manual:

&#9474; Duration                Number of service units for this performance   
&#9474;
&#9474;                         period.      


The key word being "this".

IOW, it starts counting again at period switch.  This is really easy to test.
Define a batch service class with 3 periods.  P1 with a DUR of 20000 and
P2 with a DUR of 20001.  Then submit a job that you know will run for at least
a few minutes.  You should be able to see via SDSF that the job stays in P2
for the same amount of time as P1.
