It doesn't, in our case. ntpd name resolution is built on getaddrinfo() which provides an answer but not a time remaining. Moreover, it's risky to re-resolve before using all addresses, or you might end up stuck using only the first (few) of the addresses. Anyway, this is a detail of an imaginary capability. We can hash out a solution once ntpd actually re-resolves non-pool hostnames.
