# Running Time
|
|
|
|
Find how long it has been since the program started in milli-seconds.
|
|
|
|
```sig
|
|
input.runningTime();
|
|
```
|
|
|
|
## Returns
|
|
|
|
* the [Number](/types/number) of milliseconds since the program started.
|
|
(One second is 1000 milliseconds.)
|
|
|
|
## Example: elapsed time
|
|
|
|
When you press button `B` on the microbit, this
|
|
program finds the number of milliseconds since the program started
|
|
and shows it on the [LED screen](/device/screen).
|
|
|
|
```blocks
|
|
input.input.onButtonEvent(Button.B, DAL.MICROBIT_BUTTON_EVT_CLICK, () => {
|
|
let now = input.runningTime()
|
|
basic.showNumber(now)
|
|
})
|
|
```
