2.8 Linux for System z9 and zSeries
The Linux(r) operating system does not support STP or the Sysplex
Timer.

But Linux doesn't need it, does it? It can set its software clock using
XNTP like any other Linux. It could also use the SCK instruction to
updates its TOD (virtual or real) clock as well. To the best of my
knowledge, Linux like any other UNIX type system is not dependant on the
TOD clock not "jumping around". I know that I sync my home Linux/Intel
system once a day to the Internet atomic clock (pool.ntp.org) with not
problems. I am fairly sure that Linux/zSeries could do the same.
Neither Linux, nor VSE. Also, z/OS under VM doesn't need it as well.
z/OS guests can be sysplexed only with other system under the same
hypervisor.
The only system which can use STP and/or Timer is z/OS in LPAR.
