ECS Fargate Timezone

Question

Hello,

I have tasks running on ecs fargate that I would like to modify the timezone from UTC to my actual timezone, how do I update this please, the docs do not specify how this can be done, will updating my environment variables of the task definition do the trick. The app is a dotnet application running on linux ecs fargate

Hello.

I think this can be changed by setting "TZ" in the environment variable in the ECS task definition.  
For example, if you want to set Tokyo time, you can change it by specifying "TZ" as the key of the environment variable and setting "Asia/Tokyo" as the value.  
https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task_definition_parameters.html#container_definition_environment

By the way, please note that depending on the container image used in the task definition, it may not be possible to set the environment variable even if you use "TZ".  
Check the base image documentation for how to change it.

set env var "TZ" in the task definition

```
{
  "family": "your-task-family",
  "containerDefinitions": [
    {
      "name": "your-container-name",
      "image": "your-image",
      "cpu": 256,
      "memory": 512,
      "essential": true,
      "environment": [
        {
          "name": "TZ",
          "value": "America/New_York"
        }
      ],
      ...
    }
  ],
  ...
}

```
