# Set your agent's time zone

> Set the time zone your Brilo agent uses so it books appointments, quotes opening hours, and schedules call backs in your local time rather than the wrong one.

Your agent's time zone decides what "tomorrow at nine" means. It is one picker in the **Configure**
tab, and getting it wrong is quiet: nothing breaks, appointments simply land in the wrong hour and you
find out from a customer.

## Before you start

* An agent, even an unfinished one. See [Create your first agent](/agents/create-your-first-agent).
* One minute.
* The time zone your customers are in, which is not always the one you are in.
* You will be working in your agent's **Configure** tab.

## Steps

<Steps>
  <Step title="Open the Configure tab">
    Open your agent and go to **Configure**. **Time Zone** sits under **Agent Information**, below
    **Interrupt Greeting**.
  </Step>

  <Step title="Pick the time zone your customers are in">
    Choose the zone your business operates in. If you have staff in one place and customers in
    another, pick the customers, because they are the ones saying "tomorrow morning".
  </Step>

  <Step title="Save and check a booking">
    Save, then call your agent and book a test appointment for a specific time. Open your calendar and
    confirm it landed on the hour you asked for. See
    [Test your agent yourself](/go-live/test-your-agent-yourself).
  </Step>
</Steps>

## You will know it worked when

You ask your agent to book something for ten in the morning, and it appears in your calendar at ten in
the morning. Not nine, not one in the afternoon.

## What the time zone controls

* **Appointments.** What your agent understands when a caller says a time, and what it writes into
  your calendar. See [Book appointments](/actions/book-appointments).
* **Opening hours.** Whether it treats the current moment as inside or outside your hours. See
  [Business hours and after hours](/calls/business-hours-and-after-hours).
* **Call backs.** When a call back scheduled for "this afternoon" actually goes out. See
  [Schedule a callback](/actions/schedule-a-callback).
* **Campaigns.** The hours your outbound calls are allowed to run in. See
  [What is a campaign](/campaigns/what-is-a-campaign).

## Businesses in more than one time zone

Run one agent per time zone and give each its own phone number. That way a caller who dials the number
for your Denver branch gets an agent that thinks in Denver time, and nobody has to do arithmetic on
the phone. See [Assign a number to an agent](/phone-numbers/assign-a-number-to-an-agent).

Trying to make one agent serve two zones does not work well, because the caller never says which zone
they mean.

## What else you can do here

* Set the hours your transfers and call backs are allowed to run in. See
  [Business hours and after hours](/calls/business-hours-and-after-hours).
* Set the time zone on a booking action separately, if a specific calendar runs on a different zone.
  See [Book appointments](/actions/book-appointments).
* Check your workspace time zone as well, which is what your reports are shown in.

## If it did not work

**Appointments land an hour out.** Almost always daylight saving. Confirm you picked a named city zone
rather than a fixed offset, since a named zone follows the clock change and a fixed offset does not.

**Appointments land several hours out.** The agent time zone and the calendar time zone disagree.
Check the time zone on your booking action as well as the one here. See
[Book appointments](/actions/book-appointments).

**Your agent thinks you are closed when you are open.** The time zone is right but the hours are set
against a different one. See [Business hours and after hours](/calls/business-hours-and-after-hours).

**Call backs go out at the wrong time.** Same cause. The call back uses the agent time zone, so fix
it here and the schedule follows.

## FAQ

<AccordionGroup>
  <Accordion title="How do I set the time zone for my Brilo agent?">
    Open your agent, go to **Configure**, and choose **Time Zone** under **Agent Information**. Save,
    then book a test appointment and check it lands on the right hour.
  </Accordion>

  <Accordion title="Why are my appointments booking at the wrong time?">
    In almost every case the agent time zone and your calendar time zone do not match, or a fixed
    offset was chosen instead of a named city so daylight saving is ignored. Check both, then book a
    test appointment to confirm.
  </Accordion>

  <Accordion title="Does the time zone handle daylight saving automatically?">
    Yes, as long as you picked a named zone such as America/Denver rather than a fixed offset. Named
    zones follow the clock change on their own and you never have to touch them again.
  </Accordion>

  <Accordion title="Should I use my time zone or my customers' time zone?">
    Your customers'. They are the ones saying "tomorrow at nine", and they mean nine where they are.
    If your team sits elsewhere, let the calendar handle the conversion.
  </Accordion>

  <Accordion title="Can one agent handle callers in several time zones?">
    Not cleanly, because callers do not say which zone they mean. Run one agent per zone with its own
    phone number instead. See
    [Assign a number to an agent](/phone-numbers/assign-a-number-to-an-agent).
  </Accordion>

  <Accordion title="Does changing the time zone affect appointments already booked?">
    No. Bookings already in your calendar stay where they are. The change applies to calls from that
    point on, so check any bookings taken while the setting was wrong.
  </Accordion>
