To set a time zone for your installation, set the following variable to your region, as specified in this [list of TZ database time zones](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones):

```plaintext
SYSTEM_TIME_ZONE=<tz database entry>
```

To set a time zone for logs, set the following variable to your region:

```plaintext
LOGS_TIME_ZONE=<tz database entry>
```

Examples are US/Eastern, Australia/Sydney, Australia/NSW, and America/Los_Angeles. The default is US/Eastern.

The Hyperscience platform uses both UTC and the time zones you set during installation in the ".env" file:

- _SYSTEM_TIME_ZONE_ specifies the time zone that is used in the UI.
- _SYSTEM_TIME_ZONE_ is used for _start_time_ and _complete_time_ in the API output for submissions.
- _LOGS_TIME_ZONE_ specifies the logs time zone.
- The _/admin_ section is in UTC.

We recommend keeping the database time zone in UTC to avoid unexpected time zone behavior in the system.
