I don't know about z/VM, but there is no issue of "adjusting the
time" upon the summer/winter time switch on Linux.
The Linux kernel system clock by definition always runs relative
to UTC. The concepts of local time, summer/winter time, etc, are
all implemented in the system libraries, which apply conversions
to the kernel's UTC-based time as appropriate for the current
timezone setting whenever a program asks for the local time.
The timezone can be set per process/session, with a system-wide
default. Summer/winter time switch-over dates and other conversion
details are included in the timezone definition files as used by
the system libraries.
For a more detailed explanation and further references, see "man tzset".
