ISTR that all time references in a SYSPLEX must be within a certain tolerance

If the local time source exceeded this tolerance, the ETR (STP/9037) would
guide them to the same value, or failing that , remove the system from the plex.

Mark,
What's their definition of "sync"? We (this community) have an assumed
definition -- a very good one, the Sysplex definition -- that for a variety
of reasons makes much sense. That said, if you look at other, lesser
servers they don't share that definition. They don't have Sysplex.

I agree, but the question that my management team has requested for me to find
out is whether we can use another mechanism to sync the time across the three
CEC's without STP or ETR.

You've hit the problem, we have two z196 processors that are STP
capable, but can't have the 9037's attached, and one z10 where we can
attach the sysplex timers, but that processor doesn't have the STP feature.

I believe that you can have a mixed CTN where one CEC doesn't have STP, but in
that case the external time source must be the 9037 and I'm pretty sure that at
