Looks like the client time reported by kdc.log is really wrong.

Kerberos credential cache contains the old expired ticket before the DST
change:

> klist | sed '(rename)'
Credentials cache: FILE:/tmp/krb5cc_169
        Principal: saper@EXAMPLE.ORG

  Issued                Expires        Principal

Workaround: Removing this fixes the problem
