There is a time-offset option, but this option's use is fraught
with danger as the folks who've told me of its use still have
the scars.  I'm not sure which clients have actually implemented
it.

There's a draft before the ietf dhc wg lately that implements two
options that relate this kind of information.

If you control the client and server in your local site, you
might want to consider using the site local space and designing
your own options to carry this information.
