>From my point of view, this is out of scope. Getting the hardware clock
"right" is a job that has been solved on the operating system level, using
Distributed Systems protocols like NTP.
I agree that, for many services, exact time is crucial (try to deliver a PDC
with a broken clock.), but this would be either something that
a) may be part of an operating system template mechanism, where you know
that such basic services are available or
b) is ensured through quality of service parameters (as part of the contract
or SLA between consumer and provider)
Making it an attribute seems to be the better of the two options for OCCI,
but it still doesn't make that much sense -- what does an attribute on the
clock (which way ever this attribute is structured) tell me other than that
the clock is there and in sync (with a drift of x and skew of y) at any
time, and why would I want to discover this information via the OCCI
interface?
Just my two cents.
