The freshly released busybox 1.28 has a number of DNS related
fixes for NTP btw.

      ntpd: do run the script at least once in 11 minutes
      ntpd: improve treatment of DNS resolution failures
      ntpd: mention in help text that -d can be repeated
      ntpd: perform DNS resolution out of send/receive loop. Closes 10466
      ntpd: skip over setting next DNS resolution attempt if it is not needed
