如果您的RDS MySQL实例的时区与您业务所在地域的时区不符，或者在夏令时和冬令时交替时需要校准实例的标准时间，可通过控制台或API接口修改实例的时区。本文介绍RDS MySQL实例时区的修改、验证方法和时区与UTC偏移量对照表。
应用场景
在以下场景下，您需要修改RDS MySQL实例的时区：
系统中RDS MySQL实例的时区与您业务所在地域的时区不符，例如，2021年5月30日之前购买的RDS MySQL实例的默认时区为SYSTEM，需要修改为您业务所在地域的时区。
美国、加拿大、澳大利亚、欧洲等国家在夏令时和冬令时交替时，需要您手动调整所使用的标准时间。例如，英国在由冬令时转换为夏令时时，需要将冬令时时间（UTC）修改为夏令时时间（UTC+1） 。
前提条件
您已经创建RDS MySQL实例，创建方法请参见创建RDS MySQL实例。
注意事项
时区参数修改后，需要重启实例才能生效。建议您在业务低峰期操作，并确保应用程序具有重连机制。
在RDS控制台修改时区
- 访问RDS实例列表，在上方选择地域，然后单击目标实例ID。
在左侧导航栏中，单击参数设置。
在可修改参数页签内找到default_time_zone参数，单击运行参数值列的
，在弹出的对话框中修改时区的值，完成后单击确定。说明default_time_zone参数的取值含义，请参见时区与UTC偏移量对照表。
单击提交参数，在弹出的对话框中，选择生效的时间段，完成后单击确定。
说明参数的修改未提交时，如果想取消修改，请单击撤销。
调用API接口修改时区
请求示例
本示例调用ModifyParameter接口将时区参数default_time_zone修改为+9:00。
...
// Parameter settings for API request
ModifyParameterRequest modifyParameterRequest = ModifyParameterRequest.builder()
.DBInstanceId("rm-bp1l94k5sw1zxxxxx")
.parameters("{"default_time_zone":"+9:00"}")
.forcerestart(true)
// Request-level configuration rewrite, can set Http request parameters, etc.
// .requestConfiguration(RequestConfiguration.create().setHttpHeaders(new HttpHeaders()))
.build();
...JSON格式返回结果
HTTP/1.1 200 OK
Content-Type:application/json
{
"RequestId": "6D698793-FC2B-5FC1-A6DF-33EDAD1AD6AB"
}验证时区修改结果
- 访问RDS实例列表，在上方选择地域，然后单击目标实例ID。
在左侧导航栏中，单击参数设置。
在参数修改历史页签内查看修改的时区参数值已生效。
