No. A Unix program (ntpdate or other) should reasonably be able to
expect all signals to be unblocked at startup (this might even be in
some POSIX spec or other). If some of them are blocked, the reasonable
explanation is that they have been blocked intentionally (e.g. for
debugging), and the program shouldn't try to override this. If the
signals are blocked unintentionally, it is a bug(tm) in the environment
that starts the program.
