How to find difference between two Joda-Time DateTimes in minutes

Question

Something like...

DateTime today = new DateTime();
DateTime yesterday = today.minusDays(1);

Duration duration = new Duration(yesterday, today);
System.out.println(duration.getStandardDays());
System.out.println(duration.getStandardHours());
System.out.println(duration.getStandardMinutes());

Which outputs

1
24
1440

or

System.out.println(Minutes.minutesBetween(yesterday, today).getMinutes());

Which is probably more what you're after

This will get you the difference between two DateTime objects in milliseconds:

DateTime d1 = new DateTime();
DateTime d2 = new DateTime();

long diffInMillis = d2.getMillis() - d1.getMillis();

Something like...

Minutes.minutesBetween(getStart(), getEnd()).getMinutes();

DateTime d1 = ...;
DateTime d2 = ...;
Period period = new Period(d1, d2, PeriodType.minutes());
int differenceMinutes = period.getMinutes();

In practice I think this will always give the same result as the answer based on Duration. For a different time unit than minutes, though, it might be more correct. For example there are 365 days from 2016/2/2 to 2017/2/1, but actually it's less than 1 year and should truncate to 0 years if you use PeriodType.years().

In theory the same could happen for minutes because of leap seconds, but Joda doesn't support leap seconds.
