# resetSimulation

[Built-ins](README.md) · [Labs guide](../guides/labs.md)

Canonical ID: `simulation.reset`. Nederlands: `herstelSimulatie`.

Resets a clock's tick and time to zero and pauses it. Step size and rate remain. Measurement series are not cleared.

## Signature

```text
resetSimulation(clock)
```

## Return value and behavior

A new reset clock Map.

The helper returns a new value. Use set/zet when updating a variable; the earlier value stays unchanged.

## Example

```pliro
# language: en
let clock = resetSimulation(stepSimulation(simulationClock(0.1)))
```
