I agree. Seconds is sufficient; I don't see any need to formally define
:hours (it's only used internally by our product anyhow).

I have to agree, although I note that we could, if we wanted to, define
this in terms of the FUTURERELEASE extension.

But perhaps a better place for that would be with notify mailto;, not vacation.

There's also the issue that cancellations of this sort may be very difficult
to implement. I would certainly want it to be a separate extension in any case.

Agreed as well.

I was planning to do that. Unfortunately this whole SUNW->ORCL injection thing
has me a tad preoccupied :-)
