# Time Control

#### Date and Time Displayed

Tacview displays the current date and time in the upper-left corner of the 3D view. This corresponds to the mission date and time, in UTC, as provided by the flight simulator or telemetry file:

#### UTC Offset

To display the time of a specific timezone, go to `Options` → `Time Offset`.

#### Timeline

The timeline at the bottom of the main window shows the progression of the mission. Markers indicate combat events, such as weapon releases, hits, and destruction events. The markers a grey by default and when an object is selected, events related to that object are highlighted in blue on the timeline.

#### Controlling Time with Keyboard and Mouse

At any time in Tacview, press `F1` or go to `Help` → `Controls List` to display the list of available keyboard and mouse controls.

Ensure that the 3D view is in focus (by clicking on it) before you use any keyboard controls.

#### Time Jumps

You can jump to a specific point in time by selecting `Analysis` → `Time Jump`, or by double-clicking the time displayed to the left of the playback bar.

#### Charts

When viewing a chart, hold the middle mouse button, or both the left and right mouse buttons, and drag to inspect what was happening at a specific point on the chart.

#### Weapons Deployment

In the object list, you can `Shift` + `Click` a weapon to jump to the time when it was released.

#### Flight Log

You can also double-click any entry in the [Flight Log](/tacview/getting-started/flight-log.md) to jump directly to that event.

### Time Shift

The Time Shift option moves the selected object’s telemetry forward or backward in time, without changing the shape of its trajectory.

Use this option when an object’s position data is correct, but its timing is offset. This can happen when a flight recorder clock was incorrect, when telemetry was imported from multiple sources, or when recordings were not perfectly synchronized.

Time Shift can also be used to compare performances more clearly. By aligning two aircraft at the same point in time, you can compare their trajectories, approaches, turns, or race lines as if they had started together.

Find the option at `Debriefing` → `Time Shift`

#### Real-Time Telemetry

When using Real-Time Telemetry, if playback becomes desynchronized, click the Next arrow button to return to real time.
