Is this what you meant?
```
public static void setTimeMultiplier(boolean enabled){
		if(enabled){
			TIME_MULTIPLIER = 20;
			RECORDED_TIME = System.currentTimeMillis();
		} else {
			TIME_MULTIPLIER = DEFAULT_TIME_MULTIPLIER;
		}
	}
	
	public static long currentTimeMillis(){
		if (TIME_MULTIPLIER == DEFAULT_TIME_MULTIPLIER){
			return System.currentTimeMillis();
		} else {
			return (long) (RECORDED_TIME + (System.currentTimeMillis() - RECORDED_TIME) * TIME_MULTIPLIER);
		}
	}
```
