# Running Time
Get the number of milliseconds elapsed since the script began. 1,000 milliseconds = 1 second.
Find how long it has been since the program started.
```sig
input.runningTime();
@ -8,15 +8,20 @@ input.runningTime();
### Returns
* [Number](/reference/types/number)
* the [Number](/reference/types/number) of milliseconds since the program started.
(One second is 1000 milliseconds.)
### Example: elapsed time
This code gets the elapsed time since the start of the program execution and displays it on the screen.
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
let now = input.runningTime()
basic.showNumber(now)
input.onButtonPressed(Button.B, () => {
let now = input.runningTime()
basic.showNumber(now)
})
```
