> DateTools creates a Calendar instance on every call to dateToString and timeToString. Specifically:
> # timeToString calls Calendar.getInstance on every call.
> # dateToString calls timeToString(date.getTime()), which then instantiates a new Date(). I think we should change the order of the calls, or not have each call the other.
> # round(), which is called from timeToString (after creating a Calendar instance) creates another (!) Calendar instance ...
> Seems that if we synchronize the methods and create the Calendar instance once (static), it should solve it.
