Well, yes, it can hurt.  Dann F had explicit experience with it hurting
when he was poking around with arm.  His particular issue seemed like
something we should'nt have hit, but the problem was that there were 2
NICs, the first came up, did dhcp... set the time , that caused havoc on
the second that was sleeping.

It will just take some playing to see what all falls out when the clock
moves forward or backward in a large increment.  Luckily, we're pretty
early in boot at the point in which this would happen so less things can
be affected by it.  Also, there is president for this as ntpdate does run
on ifup in normal ubuntu systems.  I'm not sure why there wasn't fallout
seen as a result in other non-maas places.

So, in summary: I'm not sure whats going to happen.

Reguarding the hwclock, We would *want* to set it IMO.
Its better to fix the problem at the source if we can.
