<p class="MsoNormal" style="margin-bottom:12.0pt">I recently saw something similar on a 2 node cluster. NTP would initially sync but then fall out of sync. Logs were showing a greater than 'x' time difference and it was restarting NTP. As a final step I
rebooted both nodes and it NTP would resync. </p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">When you did a 'utils ntp status' on the boxes it would show that the reference source was LOCL which appears to be the hardware clock. Hardware clock is used when NTP fails to sync.</p>
