[Joda-interest] Offset Value

[Guido G. <gui...@gm...>]

Hello everybody!
I have a problem which is puzzling me.
Let' s say I have a localTime of DateTime type. Now I convert it with 
the method toDateTime or withZone to another Time Zone.
I want to determine what the offset between the two Time Zones is (e.g. 
if localTime Zone is New York and convertedTime Zone is Rome I should 
get 6).
I've tried to determine the Period between the two Objects, but, since 
the result of the conversion maintains the same milliseconds value of 
the  first one, the result is "PT0S".
Can anybody help me with this?
Thank you guys for your attention!
Have a great day.
                            Guido
