This page describes those time zone settings. For cases where a fixed time zone applies In some cases, arbitrary time zones cannot be applied. Please note See [cases where a fixed time zone applies](/docs/en/time-zone#%E5%9B%BA%E5%AE%9A%E3%81%AE%E3%82%BF%E3%82%A4%E3%83%A0%E3%82%BE%E3%83%BC%E3%83%B3%E3%81%8C%E9%81%A9%E7%94%A8%E3%81%95%E3%82%8C%E3%82%8B%E3%82%B1%E3%83%BC%E3%82%B9). About Daylight Saving Time Time zones that use daylight saving time experience a deviation from standard time during the summer months. Please take note of this. ## Time Zone Type There are two main time zones that can be set in TROCCO. - [Time zone associated with user information](/docs/en/time-zone#%E3%83%A6%E3%83%BC%E3%82%B6%E3%83%BC%E6%83%85%E5%A0%B1%E3%81%AB%E7%B4%90%E3%81%A5%E3%81%8F%E3%82%BF%E3%82%A4%E3%83%A0%E3%82%BE%E3%83%BC%E3%83%B3) - [Time zone specified in various settings](/docs/en/time-zone#%E5%90%84%E7%A8%AE%E8%A8%AD%E5%AE%9A%E3%81%A7%E6%8C%87%E5%AE%9A%E3%81%99%E3%82%8B%E3%82%BF%E3%82%A4%E3%83%A0%E3%82%BE%E3%83%BC%E3%83%B3) ### Time zone associated with user information Applies to the following - **On-screen date and time display** The date and time when the time zone offset (time difference from Coordinated Universal Time) follows the time in the format and the time zone associated with the user information is applied is displayed on the screen. For example, if the time zone is set to `Asia/Tokyo`, which has a time difference of +9 hours from Coordinated Universal Time (UTC), the `time` will be displayed as follows: `2023/08/31 15:00:00 +09:00.` - **Defined value of time zone to be specified in various settings** The time zone associated with the user information is applied to the [time zone](/docs/en/time-zone#%E5%90%84%E7%A8%AE%E8%A8%AD%E5%AE%9A%E3%81%A7%E6%8C%87%E5%AE%9A%E3%81%99%E3%82%8B%E3%82%BF%E3%82%A4%E3%83%A0%E3%82%BE%E3%83%BC%E3%83%B3) specified [in the various settings](/docs/en/time-zone#%E5%90%84%E7%A8%AE%E8%A8%AD%E5%AE%9A%E3%81%A7%E6%8C%87%E5%AE%9A%E3%81%99%E3%82%8B%E3%82%BF%E3%82%A4%E3%83%A0%E3%82%BE%E3%83%BC%E3%83%B3) described below. If you want to specify a time zone different from the time zone associated with the user information, change the time zone in the respective settings screen. #### Procedure for changing the time zone associated with user information 1. Click on the area where the email address you are logging in to is displayed, then click on **User Information**. ![image](https://cdn.document360.io/3a3bae1e-f157-487f-8798-01e9d820e760/Images/Documentation/time-zone-2024-08-29-8-43-0.png) 2. Click **Edit****Time Zone Settings**. ![image](https://cdn.document360.io/3a3bae1e-f157-487f-8798-01e9d820e760/Images/Documentation/time-zone-2024-08-29-8-43-1.png) 3. Select a time zone and click **Save**. ![image](https://cdn.document360.io/3a3bae1e-f157-487f-8798-01e9d820e760/Images/Documentation/time-zone-2024-08-29-8-43-2.png) ### Time zone specified in various settings You can specify individual time zones for the dates and times you set, such as the date and time of Schedule execution or the date and time of expansion into Custom Variables. The individually specified time zone takes precedence over the time zone associated with the user and is applied when performing various settings. #### Example: Specify the time zone in the Schedule registration in ETL Configuration. 1. Click **Add Schedule** on the **Schedule Configuration** tab of the ETL Configuration Details. ![image](https://cdn.document360.io/3a3bae1e-f157-487f-8798-01e9d820e760/Images/Documentation/time-zone-2024-08-29-8-43-3.png) 2. Select any time zone and click **Save**. ![image](https://cdn.document360.io/3a3bae1e-f157-487f-8798-01e9d820e760/Images/Documentation/time-zone-2024-08-29-8-43-4.png) The registered schedule will appear in the **Schedule** tab. The **execution schedule** and **time zone** columns will reflect the information registered in the above procedure. However, the **Next Scheduled Execution** column shows the date and time converted to the time zone associated with the user. ![image](https://cdn.document360.io/3a3bae1e-f157-487f-8798-01e9d820e760/Images/Documentation/time-zone-2024-08-29-8-43-5.png) When the time zone associated with a user is changed, the date and time converted to the changed time zone will appear in the **next scheduled execution** value. ## Cases where a fixed time zone applies In the following cases, a fixed time zone is applied instead of the arbitrary time zone you set. - Cases where `Etc/UTC (+00:00)` is fixed and applicable - Data Destination Google BigQuery, Data Mart Google BigQuery - Boundary time of partitions when partitioning is set - Programming ETL - Default time zone for time classes and time modules implemented in the programming language - Cases where `Asia/Tokyo (+09:00)` is fixed - Defined values for the `time_zone` parameter of [TROCCO API](/docs/trocco-api) execution system requests - Date and time of the period for the **Transfer Time Summary and****Transfer Volume Summary on****the** TROCCO Home screen **dashboard**.
