[Libreoffice] IDL "hyper" / Java "long"

Of course, it's obvious... ;)

Max. long in Java is:
     9223372036854775807
but after pasting it into Calc we have:
     9223372036854780000

Finally I have released this extension:
http://extensions-test.libreoffice.org/extension-center/java-time-zones

Double doesn't cover long but the extension will support operations on
dates (via milliseconds) for the next few years ;)

Thank You for feedback and explanation.
