That host is just a pool.ntp.org member (and has no relation to us, quite a coincidence that the PTR shows that). It may or may not really be a CnC server. Whether or not it is, the fact you're trying to sync time to it isn't likely any reason for concern (unless it's CnC that's hiding in UDP 123 traffic and not really NTP at all, but that's probably unlikely).
