By observing the difference in values reported by chronyc serverstats
over the interval you want the average apply to. For example, this
shell script would print averages over one-minute intervals:

while chronyc -c serverstats; do sleep 60; done | \
  awk -F , '{if (l>0) print ($1-l)/60; l=$1}'

No, not easily. If the reported averages should be accurate, chronyd
would need to save the counters in a queue.

This is better done externally by tools specialized in processing time
series data like rrdtool.
