I believe you are correct that SNTP servers will not change when we "fall
back" this weekend.

My understanding is that the Time Zone (QTIMZON) system value (rather than
QUTCOFFSET) controls time processing after V5R2.  In fact, if I understand
properly, there are going to be some PTF's to install before the "spring
forward" next year to handle the DST changes for next year.

AT V5R2 and prior, DST changes had to be done manually, although there are
readily available utilities to take care of it.  I used this one to take
care of it until I upgraded to a V5R3 box last fall.
