 The YAML below defines an AdvancedCronJob. It will create a BroadcastJob every minute, which will run a job on every node.
+
+## Time zones
+
+All CronJob schedule: times are based on the timezone of the kruise-controller-manager by default,
+which means the timezone set for the kruise-controller-manager container determines the timezone that the cron job controller uses.
+
+**FEATURE STATE:** Kruise v1.3.0
+
+However, we have introduce a `spec.timeZone` field in v1.3.0.
+You can set it to the name of a valid time zone name. For example, setting `spec.timeZone: "Etc/UTC"` instructs Kruise to interpret the schedule relative to Coordinated Universal Time.
+
+A time zone database from the Go standard library is included in the binaries and used as a fallback in case an external database is not available on the system.

 上述 YAML 定义了一个 AdvancedCronJob，每分钟创建一个 BroadcastJob 对象，这个 BroadcastJob 会在所有节点上运行一个 job 任务。
+
+## 时区
+
+默认情况下，所有 AdvancedCronJob schedule 调度时，都是基于 kruise-controller-manager 容器本地的时区所计算的。
+
+**FEATURE STATE:** Kruise v1.3.0
+
+不过，在 v1.3.0 版本中我们引入了 `spec.timeZone` 字段，你可以将它设置为任意合法时区的名字。例如，设置 `spec.timeZone: "Asia/Shanghai"` 则 Kruise 会根据国内的时区计算 schedule 任务触发时间。
+
+Go 标准库中内置了时区数据库，作为在容器的系统环境中没有外置数据库时的 fallback 选择。
