- Creation of new `CronJob` objects containing `TZ` or `CRON_TZ` in `.spec.schedule`, accidentally enabled in `v1.22`, is now disallowed. Use the `.spec.timeZone` field instead, supported in `v1.25+` clusters in default configurations. See https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/#unsupported-timezone-specification for more information. ([#116252](https://github.com/kubernetes/kubernetes/pull/116252), [@soltysh](https://github.com/soltysh))

<p>
Type definitions may be used to define different boolean, numeric,
or string types and associate methods with them:
</p>

<pre>
type TimeZone int

const (
	EST TimeZone = -(5 + iota)
	CST
	MST
	PST
)

func (tz TimeZone) String() string {
	return fmt.Sprintf("GMT%+dh", tz)
}
</pre>

### Feature

- Added Timezone column in the output of the 'kubectl get cronjob' command.
   ([#122231](https://github.com/kubernetes/kubernetes/pull/122231), [@ardaguclu](https://github.com/ardaguclu))

func writeSuccessNoContent(w http.ResponseWriter) {
	writeResponse(w, http.StatusNoContent, nil, mimeNone)
}

// writeRedirectSeeOther writes Location header with http status 303
func writeRedirectSeeOther(w http.ResponseWriter, location string) {
	w.Header().Set(xhttp.Location, location)
	writeResponse(w, http.StatusSeeOther, nil, mimeNone)
}

func writeSuccessResponseHeadersOnly(w http.ResponseWriter) {

- Promoted CronJob's TimeZone support to beta. ([#111435](https://github.com/kubernetes/kubernetes/pull/111435), [@soltysh](https://github.com/soltysh))

- The infrastructure for contextual logging is complete (feature gate implemented, JSON backend ready). ([#108995](https://github.com/kubernetes/kubernetes/pull/108995), [@pohly](https://github.com/pohly))
- This adds an optional `timeZone` field as part of the CronJob spec to support running cron jobs in a specific time zone. ([#108032](https://github.com/kubernetes/kubernetes/pull/108032), [@deejross](https://github.com/deejross))
