NTP is designed to synchronize computer clocks to a common time base.

The most commonly used timebase is UTC acquired over a network or via a
radio ref-clock such as GPS. It's cheap. It's ubiquitous.

A nice side effect of using UTC as your timebase is that your clocks
will be set to the correct time.

Sure, but there are definitely applications where TAI are preferred to UTC.

The OP did not state a preferrence for TAI over UTC.

The OP _did_ repeat the old misguided "all I care about is
synchronization" meme about NTP. This is frequently uttered by people
who want to operate a stable time island and want to have it for free.

NTP needs a stable time base / frequency reference / what ever you
want to call it to achieve the best possible clock stability. Without
one your clocks are like a herd of kittens playing follow the leader.

UTC is ubiquitous and cheap. A stand alone rubidium based PPS source
will cost you at least $1K + the cost of integration.
