In the middle tends to be a more moderate solution which involves a mix of time transmission methods from a variety of geographically and/or network diverse sources. Taking time from the public trusted ntp servers and adding lower cost GPS receivers at diverse points in your network seems like a good compromise in the middle. That way, only coordinated attacks will be successful.
Instead, just rely on atomic clocks operated by you. They are not so expensive (several thousand dollars) and should be accurate enough without adjustment for hundreds of years. There can be no coordinated attacks. They may be remotely accessed through secured NTP. Masataka Ohta
