STP ETS scheduled syncronization feature request

To keep multiple STP networks (at different geographical locations) synchronized in parallel to any adjustments in time from the ETS (External Time Server) we need to be able to specify the occurrences that the PTS quarries the ETS.

o This can either be specified by the customer in the Sysplex Time panels on the SE or built into the microcode.

o An example would be “Every hour at **:30 (30 mins past the hour) query the ETS & begin any steering required.

o The issue is not the fact that STP steers the 1 second offset in time over a period of roughly 7 hours; the issue is more with our STP networks starting to steer time at different points in an hour since they all had the CTN configured at different times.

o With active-active applications increasing in our environment that reach across SysPlex boundaries at multiple sites (so multiple STP networks), the requirement to keep time steering uniform is critical.
