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

You may consider using Joda time's DateTimeComparator.getTimeOnlyInstance() for a comparator that will compare two Joda dates based only upon the times.

For example:

DateTimeComparator comparator = DateTimeComparator.getTimeOnlyInstance();
comparator.compare(date1, date2);

See http://joda-time.sourceforge.net/api-release/org/joda/time/DateTimeComparator.html#getTimeOnlyInstance()
