Correct. And, springing forward from -8 (PST) yields -7 (PDT),
which was the actual time zone offset of the system on which I
executed the demo program:

LOCAL TIME = GMT TOD + CVTLDTO - CVTLSO
CVTLDTO - CVTLSO = LOCAL TIME - GMT TOD
CVTLDTO = LOCAL TIME - GMT TOD + CVTLSO
GMT: 22:57:14.9007710000 2008/03/10 (UTC [most call it GMT])
LOCAL: 15:56:51.9007710000 2008/03/10 (Pacific Daylight Time)
------------------- =====================
-07:00:23 (LOCAL TIME - GMT TOD) = (CVTLDTO - CVTLSO)
+ + :23 (LSO [actual, current value])
---------
-07:00:00 (LDTO)
