# Timing tower card

> Canonical HTML: https://screenrig.ai/docs/cards/timing-tower/

A motorsport timing tower: every car by position with its team colour, code, tyre, last lap in the timing colours and the interval or gap, the lap count or session clock, and the track's flag. Reads a race feed, or timing written to the data store.

## Views and forms

Views: canvas, corner, chip. Canvas forms: landscape, portrait, square, strip, tower.

[Card views, themes and publishing](/docs/cards/). [Browse the gallery](/apps/#cards).

## Data and privacy

Feed: `screenrig.game.motorsport/v1`.

Feed documents carry source attribution. The Player supplies the feed to the card.

## Properties

For theme, background, accent and position, see [Common properties](/docs/cards/#common-properties).

Set static properties in `params`. Bind `data` to a project card data key for live values; that document holds only dynamic properties. Without a data key, put the complete configuration in `params`. Nested rows describe the contents of their parent property.

### Static properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `title` | string | `""` | maxLength: `40` | Empty uses the competition's name. |
| `gapMode` | string | `"interval"` | `"interval"`, `"gap"` | Which figure leads a race row: the interval to the car ahead or the gap to the leader. |
| `hour12` | boolean | `false` |  |  |
| `timeZone` | string, null | `null` |  |  |

### Dynamic properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `game` | object, null | `null` |  | The session as a screenrig.game.motorsport/v1 document, for venues and clubs: a scoreboard bridge or an agent writes it to the data store. Used when no feed is attached. |
