Previously it does:

> $ oc get events -w
> LAST SEEN                       FIRST SEEN                      COUNT     NAME                             KIND                    SUBOBJECT   TYPE      REASON                  SOURCE                            MESSAGE

Comment 6 Juan Vallejo 2018-12-18 19:39:10 UTC

This is working as intended. The output of `events` was recently improved in https://github.com/kubernetes/kubernetes/pull/66643.

From the patch notes:
> 4. The duration fields were changed to be the more precise output introduced for job duration (2-3 sig figs)

With regards to backwards compatibility, we do not consider "human-readable" output to have an "api guarantee". Also see [1].
