> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

## time<T>(valueToMeasure: () -> T): TimeMeasurement<T>

Executes the input function and returns a `TimeMeasurement` object that contains the start and end
time for the execution of that function, as well the result of the function.

### Parameters

<table><colgroup><col> <col></colgroup><thead><tr><th>Name</th><th>Description</th></tr></thead><tbody><tr><td><p><code>valueToMeasure</code></p></td><td><p>A function to pass to <code>time</code>.</p></td></tr></tbody></table>

### Example

This example passes `wait` and `sum` functions (defined in the header), which return their results
in `TimeMeasurement` objects.

```Dataweave
%dw 2.0
output application/json
fun myFunction() = dw::Runtime::wait("My result",100)
fun myFunction2() = sum([1,2,3,4])
---
{ testing: [
    dw::util::Timer::time(() -> myFunction()),
    dw::util::Timer::time(() -> myFunction2())
  ]
}
```

#### Output

```XML

  "testing": [
    {
      "start": "2018-10-05T19:23:01.49Z",
