Install the devscripts package if you've not already done so.
Then:
apt-get source ntp-dev
cd ntp-dev-4.2.7p447
Now edit ./debian/control and fix the Provides
I installed the ntp-dev package for Debian as recommended here to get
better resolution for the offset and jitter values.
Unfortunately this package is hardcoded to conflict with ntp, and I
have another package installed that depends on ntp and ntpdate.
I understand that the developers want to

There is no ntp-dev package in Debian. The Conflicts was put in the
ntp-dev package by whoever built it. You can take it out or to use

Well, I chose the Trible Accutime just to have access to a PPS
Your Accutime does provide a TTL PPS signal (by the way, PPS capable
GPS receivers are quite inexpensive and common these days) but USB
isn't the right way to import the signal.

Why? The time is copied to the CMOS clock regularly, and one could
