According to the Olsen timezone database, Europe/Busingen is an alias for
Europe/Zurich.  So while it's an interesting question why the client side
is sending "Europe/Busingen" not "Europe/Zurich", you should get the same
result either way.  And it's not hard to imagine that there might be
logic somewhere inside Java that causes one to be substituted for the
other.

However, a look into the Olsen source files suggests that Europe/Busingen
was only added as a zone name in 2011.  When was your last server update?
I don't know whether EDB relies on the system tzdata package, so either
the postgres package or the tzdata package might be old ...
