FWIW.
We got our 3 9037-1 approx 3 years ago for USD1000 a piece.
Two online, one in case the other breaks.
None have broken. They are set to synchronize with
Boulder NIST once a day. We've had zero problems and zero issues.
Consequentially, the NTPD daemon on z/OS always serves up the
correct time to all who ask.

That's certainly a viable solution, but...
In some environments, running the NTP server on the mainframe will do a
very good job of keeping all your other systems consistent...consistently
wrong. I can't speak to STP, since I know very little about this new
feature. But traditionally, synchronizing a mainframe environment to an
external time source such as NIST or GPS requires an ETR[1]. I don't know
what the current price of that device runs, but I've seen figures as high
as $35K bandied about in this list for what is essentially a glorified PC.
What's your response to the CIO after you've requested an ETR and he/she
replies along the lines of: "You want me to spend $xxx for something that
every other system in my shop can do for free???!!!"

[1] IIRC, the Sysplex Timer does *not*, by itself, synch to an external
time source. It merely keeps the TOD clock in all systems in the plex
synchronized.
