Start the timer
```
    Timer::start();     
```
Mark a place as a lap (the timer will continue counting time after returning the difference between the start and this lap)
```
    $duration = Timer::lap();
```
where $duration is in milliseconds
If you want the duration between this lap and the last one, send this constant as a parameter:
```
    $duration = Timer::lap(Timer::FROM_LAST_LAP);
```
To stop the time and get the duration from the beginning (the start)
```
    $duration = Timer::stop();
```

To stop the time and get the duration from the last lap

    $duration = Timer::stop(Timer::FROM_LAST_LAP);
