# toc
|
|
|
|
> Return a high-resolution time difference.
|
|
|
|
<section class="usage">

|
## Usage
|
|
|
|
```javascript
|
|
var toc = require( '@stdlib/time/toc' );
|
|
```
|
|
|
|
#### toc( time )
|
|
|
|
Returns a high-resolution time difference, where `time` is a two-element `array` with format `[seconds, nanoseconds]`.
|
|
|
|
```javascript
|
|
var delta = toc( [ 100, 123456789 ] );
|
|
// returns [<number>,<number>]
|
|
```
|
|
|
|
Similar to `time`, the returned `array` has format `[seconds, nanoseconds]`.
