1 Answer. The clock in a container is the same as the host machine because it’s controlled by the kernel. The timezone is controlled by the OS layer tho and so may be different in the container. You can mount in the time zone file to overcome this. Synchronization of clocks across machines is a complicated topic.Kubernetes uses kernel throttling to implement CPU limit. If an application goes above the limit, it gets throttled (aka fewer CPU cycles). Memory requests and limits, on the other hand, are implemented differently, and it’s easier to detect.
