Clocks on ubuntu longevity cluster 172.23.105.{61,83} are out of sync

During investigation of MB-24455, I found that the clocks of at least two nodes in the 172.23.105.

cluster are out of sync by ~13 seconds. This makes it very hard to correlate events occurring between the different nodes.

For tests which aren't explicitly scenarios where clocks are out of sync, could I request that all test clusters have NTP installed and configured?
