How do I calculate the elapsed time of an event in java? [duplicate]

Answer 1

Apache Commons-Lang also has the StopWatch class suited just for your purpose. It uses System.currentTimeMillis(), so you'll still have resolution problems, but you can pause and do lap times and such. I use it as standard now for event stats.
