Create a 'timer' in Java to measure the duration of some code in milliseconds and minutes.

calculateDurationOfATask.java

// Get the current system time to calculate duration
long startTime = System.currentTimeMillis();

// Do logic here

// Get the end time and calculate duration
long endTime = System.currentTimeMillis();
long durationInMs = endTime - startTime;
long durationInMins = durationInMs/60000;

logger.debug("This script took " + durationInMs + " ms or " + durationInMins + " minutes to run.");
