Re: [cti-cybox] adding CybOX timestamp attribute information

[John-Mark Gurney <jmg@newcontext.com>]

So, I guess you'd like to have additional precisions that are less than a second?  (Say millisecond)  And then an uncertainty value, like in you're case, 3 or 2.648.

I think including the offset is a bit much, as you can just add/subtract the offset value to the time stamp.

Yes.  This is also sometimes expressed as uncertainty.
Precision usually denotes essentially the number
of decimal points in the timestamp.  Uncertainty
tells you in absolute terms, how much that value
might deviate from a designated reference.

For example, my NTP monitor tells me that my
desktop is offset 1.702 milliseconds from the
Naval Observatory's reference tick.usno.navy.mil,
with a jitter (essentially uncertainty) of 2.648 ms.

Or do you mean you'd like to add a field/attribute to the Time object to denote if the time stamp source was properly synchronized (and possibly what source it was synchronized to)?
