The other issue here might be that the server didn't reply with this
option at all. Which itself might be because we didn't explicitly
request it, or because it just doesn't have that option set. For
example, the office DHCP servers return the NTP server option, but
wireless routers usually do not. This is what just happened to me when
I switched to a wireless connection here at the office. I suspect that
apps will have to have intelligent fallbacks.
