Distributed time is tricky, but it depends on what the intended use is. Under normal operation it will only move forward, for example.<p>&gt; VM live migration &quot;pause&quot;?<p>System clock will take a larger step than usual. It won&#x27;t go backwards.<p>&gt; daylight savings change?<p>None. System clock is UTC for a reason.<p>&gt; ntp updates which change the time?<p>NTP only drifts the clock (under normal operation).
