If you are in U.S. Central time, your UTC is definitely off by one hour.
Which makes all the other systems clocks to be off by 1 hour. We are in
U.S. Central - Dallas, TX. On our z/OS system, the D T command responds

RESPONSE=LIH1      IEE136I LOCAL: TIME=11.44.49 DATE=2013.308  UTC:
TIME=17.44.49 DATE=2013.308

You displays are an hour behind ours. And I am certain that mine are
correct because my boss has not been beating me up <grin/>.

Unfortunately, I am not z/VM literate enough to know what you could have
done in the SYSTEM CONFIG to cause z/VM to report the UTC hardware clock
incorrectly. Hopefully an IPL will make it all better.

This is clearly another case of too many mad scientists, and not enough
hunchbacks.
