Compare only the time portion of two dates, ignoring the date part

Question

What\'s a good method to, given two Date objects, compare the difference between their time portion only, completely ignoring Year, Month and Day?

It\'s quite the op

Answer 1

If JODA is not an option, one of the shortest approaches is probably to convert the time to strings and then compare them.

DateFormat df = new SimpleDateFormat("HHmmssSZ");
df.format(date1).equals(df.format(date2));
