Answer 1

You can use standard Java api calls:

System.nanoTime()
System.currentTimeMillis()

Answer 2

An easier approach -

Date interestingDate = new Date();

different in milliseconds between the actual current date and interestingDate by doing:

(new Date()).getTime() - interestingDate.getTime();
