Need help to convert time when it's selected to it's item (JAVA)

Question

https://github.com/Xares01/TimeZoneWorld2/blob/master/app/src/main/java/com/example/jimjohansson/timezoneworld/CurrentTimeActivity.java https://github.com/Xares01/TimeZoneWorld2/blob/master/app/src/main/res/values/strings.xml

I have a spinner that includes country names. The current time should be converted when it's selected to it's country name.

Need help converting to Finnish time when it's selected to "Finland".
Right now I have Swedish time. I have defined the Finnish item from strings.xml.
