How to get the time difference between 2 dates in millisec using JodaTime

Question

I'm going to design an application, in which I need to get the exact time difference between two dates. Ex:

Date1:31/05/2011 12:54:00
Date2:31/05/2011 13:54:00

I tried using getTime() but I didn't get exact result.

The expected output for the above inputs is 3600000 (60 * 60 * 1000) millisec but I'm getting 46800000 (13 * 60 * 60 * 1000).

When I went through different java forums people are suggesting to use JodaTime.

Still I'm unable to get the exact result.

The timezone on I'm working is London(GMT).

Init two dateTime and use Period :

DateTime dt1 = new DateTime(2013,9,11,9,58,56);
DateTime dt2 = new DateTime(2013,9,11,9,58,59);
Period p = new Period(dt1, dt2, PeriodType.millis());

To get difference in milliseconds :

System.out.println(p.getValue(0));
