I don't think that NTP is what it's using here. Even if you're signing with your own certificate, the code signature includes a signed timestamp, signed by an Apple certificate. Presumably codesign needs to contact Apple's servers to send them a sha-1 hash and receive back a signed timestamp of that hash.

(Probably it does so by an HTTP request to timestamp.apple.com --- just guessing, from the contents of Security.framework/Versions/A/Resources/TimeStampingPrefs.plist.)
