# Changing the Time Zone

The time zone of a Tmedia unit, such as the TMG800 or TMG3200, is configured on the Linux host using the **`tzselect`** command.

**The following is provided as a sample of how to configure a time zone:** NOTE: User-typed parameters are shown in red.

| `[root@TB005375 ]# tzselect<br> Please identify a location so that time zone rules can be set correctly.<br> Please select a continent<br> 1) Africa<br> 2) Americas<br> .<br> .<br> .<br> 10) None - I want to specify the time zone using the Posix TZ format.<br> #?<span style="color:red">2</span><br> <br> Please select a country.<br> 1) Anguilla<br> .<br> .<br> .<br> 10) Canada<br> .<br> .<br> .<br> 51) Virgin Islands (US)<br> #?<span style="color:red">10</span><br> <br> Please select one of the time zone regions.<br> 1) Newfoundland Time, including SE Labrador<br> .<br> .<br> .<br> 7) Eastern Time - Quebec - most locations<br> .<br> .<br> .<br> 27) Pacific Time - north Yukon<br> #?<span style="color:red">7</span><br> <br> The following information has been given:<br> Canada<br> Eastern Time - Quebec - most locations<br> <br> Therefore TZ= ‘America/Montreal’ will be used.<br> Local time is now: Wed Aug 19 08:49:01 EDT 2009.<br> Universal time is now: Wed Aug 19 08:49:01 UDT 2009.<br> Is the above information OK?<br> 1) Yes<br> 2) No<br> #?<span style="color:red">1</span><br> <br> You can make this change permanent for yourself by appending the line<br> TZ= ‘America/Montreal’; export TZ<br> to the file ‘.profile’ in your home directory; then log out and log in again.<br> <br> Here is the TZ value again, this time on standard output so that you<br> can use the /usr/bin/tzselect command in the shell script<br> America/Montreal<br> [root@TB005373 ]#<br>` |

The above set the timezone for the bash shell only. To configure the time system-wide, manually change the file /etc/localtime to point to the right timezone.

**$ rm /etc/localtime**

**$ ln -s /usr/share/zoneinfo/\<Your Timezone> /etc/localtime**

Example:

**$ ln -s /usr/share/zoneinfo/America/Fortaleza /etc/localtime**

You can check for the correct timezone name inside that directory "/usr/share/zoneinfo/../..".

**You need to restart Toolpack for it to apply the changes.** E.g. Timestamps in toolpack logs.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://tmediadocs.telcobridges.com/other-pages/operations/changing-the-time-zone.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
