### Feature

- Kubeadm: generate CA certificates with a start time that is offset 5 minutes in the past relative to the current system time to workaround cases of clock desync.

the Go 1.23 behavior.

### Go 1.23

Go 1.23 changed the channels created by package time to be unbuffered
(synchronous), which makes correct use of the [`Timer.Stop`](/pkg/time/#Timer.Stop)
and [`Timer.Reset`](/pkg/time/#Timer.Reset) method results much easier.
The [`asynctimerchan` setting](/pkg/time/#NewTimer) disables this change.
There are no runtime metrics for this change,
This setting will be removed in Go 1.27.
