I created a cluster using this change: |
Fixes cockroachdb#62063 In cockroachdb#31577 we switched to `chrony` for AWS, but not for CGE. By default they GCE clusters based on Ubuntu 16.04 use `ntp`. This patch installs `chrony` (and automatically removes `ntp`) on GCE and configures `chrony` to use Google's time server. Release note: None

The optional CI failures don't look related, but I can rebase again, just in case. |

Sounds the same to me. Thank you! |

Interesting. We frequently see clock offset panics in our attempts at long-running roachtests such as #47652. I had poked at that in the past and never got anywhere, but maybe this will help. Either way thank you for looking into this! |

There was a problem hiding this comment.
I thought GCE VMs had good time synchronization out of the box that obviated the need for chrony. My knowledge is admittedly a few years out of date. I'm fine to see if this helps.
