I don't understand this one.  What's an EntireX server.

o How did it get it wrong?

o Didn't it use the TIME macro?

o Did it read the offset parameters from CVT at startup
  and forget to refresh them?

o Did it STIMER to the start of the window and overlook
  the SET TIMEZONE?

o Did it use STIMER DINTVL= when STIMER LT= would have
  been proper?

o What happens with an outstanding STIMER LT= when the
  clock is advanced/retarded for Daylight Saving Time
  - From the console?
  - By ETR or STP?

In which of these cases does z/OS DTRT?

Is there so little information in the RM that a RCF
is appropriate?
