# Timezone

> What the account timezone affects and what stays in PMS time.

PX stores the underlying timestamps for every reservation in UTC. The **timezone** setting on the Account Preferences card controls how those timestamps display in the UI.

## How to set it

1. Open **Settings**.
2. In the **Account Preferences** card, open the **Timezone** dropdown.
3. Pick from the US timezone list:
   * Pacific (US/Pacific)
   * Mountain (US/Mountain)
   * Central (US/Central)
   * Eastern (US/Eastern)
   * Alaska (US/Alaska)
   * Hawaii (US/Hawaii)
4. PX shows a *"Timezone updated successfully"* toast.

Saving is automatic. There is no Save button.

## What the timezone affects

| Surface                                               | Affected |
| ----------------------------------------------------- | -------- |
| Property detail - reservation arrival/departure dates | Yes      |
| Audit results - arrival/departure                     | Yes      |
| Findings - detected/fixed timestamps                  | Yes      |
| Home dashboard - trend chart                          | Yes      |
| Issue detected/fixed dates                            | Yes      |

## What it does not affect

| Surface                           | Reason                                                         |
| --------------------------------- | -------------------------------------------------------------- |
| Stored timestamps in the database | Always UTC. Timezone is display-only.                          |
| The PMS itself                    | PX is read-only against your PMS.                              |
| Business model activation date    | Stored as a date, not a timestamp - timezone-agnostic.         |
| Audit date range pickers          | The pickers select calendar dates regardless of timezone.      |
| Audit PDF exports                 | Exports use the user's display timezone at the time of export. |

## Why only US timezones?

The current dropdown is constrained to US timezones because PX's customer base is US-centric. Reach out to [support@pxaccounting.com](mailto:support@pxaccounting.com) if you need a non-US timezone.

## Edge cases

* **Daylight saving time** - PX handles DST automatically. The timezone you pick is the IANA zone (US/Pacific, etc.), not a fixed offset.
* **Properties in a different timezone from your account** - timezones are account-level today, not per-property. Bookings still display in your account timezone, even when the property is elsewhere. PMS-reported check-in/check-out times are unaffected.
* **Multi-user accounts** - the timezone setting is per-account, not per-user. If multiple people work in your account from different cities, they all see the same display timezone.
