I think Google uses chrony instead of NTP
- creatonez 10mo agoGoogle doesn't use chrony specifically, just an algorithm that is somewhat chrony-like (but very different in other ways). It's called Google TrueTime.
- secondcoming 10mo agoOh right. Their cloud-init script uninstalls NTP and installs chrony each time our VMs boot
- creatonez 10mo agoAh yeah. For VPS tenants it makes sense they would default to Chrony. They have a public facing pool of NTP servers at `time.google.com`, and for tenant use they provide `metadata.google.internal`, which is probably where the Chrony config file points. IIRC TrueTime is not actually open source and is only used internally on their infrastructure.
