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

Question

Below is the method I wrote    public List lt Map lt String  Object gt  gt  loadNotYetInEmployee int shift  Date date          int transitionVal  String type  User user         DateTime datetime   new DateTime date       datetime   datetime              plus Period minutes shiftTiming getSession1InTime           List lt Map lt String  Object gt  gt  result   new ArrayList lt Map lt String  Object gt  gt          sql   SqlMapUtils getSql  attendance attendancestatus latein               parameters       result   getJdbcTemplate   queryForList sql       for  int i   0  i  lt  result size    i              Date punchInTime    Date  result get i  get  punchtime            DateTime punchTime   new DateTime punchInTime             return result      Now from my method you can see I have a Joda-Time DateTime object in object named datetime and from my result I am getting one timestamp which I am converting to jodatime punchTime  Now I want to find out the diff between these two dates  how do I do that

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

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
