Hi, Ann.
If you have the 'prompt' IPL option enabled, when you first bring up CP
it asks you (prompts....) for the date and time. I am unaware of any
optional piece of hardware that would allow VM to automatically set it's
clock via an accurate electronic source such as the Navy Observatory.

I am not sure what the options are for external timers and I think the
z9's and probably z10's have some new way of obtaining time.
We currently have external timers that are somehow magically connected
to the zVM lpars. The timers obtain time from a naval observatory.
Anyway, electricians managed to kill some of the mainframe cables
(copper melts). They are replacing the cables to the timers this
weekend.
I am wondering how to verify the new cables work. I always thought (I
could be wrong) zVM obtained the time from the hardware (HMC? SE?).
